Question 1

Arrange the elements Ba, Be, and Ca in order of increasing first ionization energy based upon their position on the periodic table.

Accepted Answer

First ionization energy generally increases across a period (from left to right) and decreases down a group (from top to bottom) on the periodic table. Be (Beryllium) is to the left of Ca (Calcium) and Ba (Barium) is below both in the same group, making Ba have the lowest first ionization energy and Be the highest.

Question 2

Which species shown below is largest?

Accepted Answer

The size of an atom or ion is determined by the number of protons in its nucleus and the amount of electron shielding. Cs has the largest number of protons (55) in its nucleus out of all the options, and also has electron shielding from its 6 energy levels.

Question 3

Question 4

Accepted Answer

The answer of Arrange the following species in order of...

Question 5

Arrange the following elements in order of increasing ionization energy. O, Mg, He

Accepted Answer

Ionization energy generally increases across a period (from left to right) and decreases down a group (from top to bottom) in the periodic table. Helium (He), being a noble gas with a complete outer shell, has the highest ionization energy. Magnesium (Mg) has a lower ionization energy than oxygen (O) because it is to the left of oxygen in the same period, making the correct order Mg < O < He.

Question 6

Given the three statements below, pick the best answer. I. The Z_eff for the highest energy electron in Be is higher than the Z_eff for the highest energy electron for N. II. The second ionization energy for Mg is greater than the first ionization energy of Na. III. The species O^{2 -}, Ne, and Na are isoelectronic.

Accepted Answer

II is true because the second ionization energy for Mg involves removing an electron from a stable, full s-orbital, which requires more energy than removing the first electron from Na, which is in a less stable, partially-filled s-orbital. I is false because the effective nuclear charge (Z_eff) for the highest energy electron in Be is actually lower than that for N, due to N having more protons and a higher nuclear charge. III is false because O^2- (with 10 electrons), Ne (with 10 electrons), and Na^+ (with 10 electrons) are isoelectronic, not O^-, Ne, and Na.

Question 7

The answer which correctly arranges the species N, NS1U1P1 - S1S1P0, OS1U1P1+S1S1P0, FS1U1P12+S1S1P0 in order of increasing ionization energy is:

Accepted Answer

The ionization energy generally increases from left to right across a period and decreases from top to bottom in a group. Therefore, we can arrange the given species in order of increasing ionization energy as: N^- < N < O⁺ < F²⁺. So, the correct option is C.

Question 8

Which of the following is true? I. A neutral atom is larger than its corresponding cation. (for example: Na > Na⁺) II. A neutral atom is larger than its corresponding anion. (for example: O > O^{2 -}) III. Ionic radii increase down a group. (for example: Li⁺

Accepted Answer

I. True, because when an atom loses an electron to become a cation, its electron cloud contracts due to a decrease in electron-electron repulsion and an increase in the effective nuclear charge per electron. III. True, because as you move down a group in the periodic table, atoms have more electron shells, making their ionic radii larger. II is false because an anion, which gains electrons, is larger than its neutral atom due to increased electron-electron repulsion.

Question 9

Which of the following processes listed below represents the experiment for measuring an ionization energy ?
("E" represents a neutral E lement, "M" represents a M etal cation and "X" represents a nonmetal anion)

Accepted Answer

Ionization energy is the energy required to remove an electron from a neutral atom in the gas phase. Choice B correctly represents this process, where a neutral element (E) in the gas phase absorbs energy to release an electron, becoming a positively charged ion.

Question 10

Arrange the elements Ne, P and K in order of increasing first ionization energy .

Accepted Answer

The first ionization energy increases as we move from left to right in the periodic table and decreases as we move down a group. 
Therefore, K with a valence electron in the fourth energy level and P with a valence electron in the third energy level have lower first ionization energies compared to Ne with a full valence shell in the second energy level. 
Thus, the order of increasing first ionization energy is K < P < Ne.

Question 11

Which answer below correctly lists the atoms shown in order of increasing first ionization energy?

Accepted Answer

First ionization energy increases across a period from left to right and decreases down a group.

Question 12

Which of the series written below is in order of increasing first ionization energy (atoms with the smallest ionization energy first)?

Accepted Answer

The first ionization energy generally increases across a period and decreases down a group. In option C, Ca is in Group 2, S is in Group 16, and F is in Group 17, which follows the trend of increasing ionization energy across a period.

Question 13

Which series of species shown below is arranged in order of increasing ionization energy?

Accepted Answer

Ionization energy generally increases across a period and decreases down a group. In choice A, Li < Si < Cl < Ar⁺ follows this trend, as ionization energy increases from left to right across the periodic table.

Question 14

Listed below are three rankings of atoms or ions in order of increasing ionization energies. Pick the best answer.
I. Li
II. P
III. Al

Accepted Answer

All three rankings are correct. Ionization energy increases from left to right across a period and decreases from top to bottom within a group.

Question 15

Arrange the following elements in order of increasing first ionization energy . Br, Cl, Se

Accepted Answer

First ionization energy generally increases across a period (due to increasing nuclear charge) and decreases down a group (due to increasing atomic radius). Se is in the same period as Br and Cl but in a group to the left, making its ionization energy the lowest. Cl is to the right of Br in the same period, making its ionization energy the highest. Therefore, the order is Se < Br < Cl.

Question 16

Listed below are three rankings of atoms or ions in order of increasing ionization energy. Pick the correct answer.
I. B
II. C
III. Al

Accepted Answer

According to the periodic table, the ionization energy generally increases from left to right and from bottom to top. Therefore, Al has the highest ionization energy, followed by C, and then B. This means that statement III is true and statement II is also true, while statement I is false. Therefore, the correct answer is choice C.

Question 17

Which series shown below is correctly arranged in order of increasing ionization energy?

Accepted Answer

The answer of Which series shown below is correctly arranged...

Question 18

Which species shown below is largest?

Accepted Answer

Indium (In) is the largest species because it is a neutral atom with more electron shells compared to the other species, which are either ions or have fewer electron shells.

Question 19

Which series shown below is correctly arranged in order of increasing ionization energy?

Accepted Answer

Ionization energy generally increases across a period from left to right and decreases down a group. In option C, Li < B < N < F is correctly arranged as ionization energy increases across the period from Li to F.

Question 20

Element "Q" is a third period element and has the following successive ionization energies. What is element "Q"? IE₁ IE₂ IE₃ IE₄ IE₅ IE₆ 577 kJ/mol 1816 kJ/mol 2744 kJ 11,576 kJ/mol 14,829 kJ/mol 18,375 kJ/mol

Accepted Answer

The large jump in ionization energy from the third to the fourth ionization energy indicates that element "Q" has three electrons in its outer shell. This characteristic is consistent with aluminum (Al), which is in the third period and has three valence electrons.
