d) Nickel
4. Which element has the largest ionization energy in the following set:
a) Scandium
b) Arsenic
c) Cobalt
d) Zinc
5. What is the mass number of an atom with 15 protons, 18 electrons, and 17 neutrons?

Answer 1

The element with the largest atomic radius is Rb (Rubidium). The charge of manganese when it contains 21 electrons is +3. The element with the largest electronegativity among the given options is Fluorine (F). The element with the largest ionization energy in the given set is Zinc (Zn). The mass number of an atom with 15 protons, 18 electrons, and 17 neutrons is 32.

Step-by-step explanation:

1. The element with the largest atomic radius is Rb (Rubidium). As you move down a group in the periodic table, the atomic radius increases.

2. The charge of manganese when it contains 21 electrons is +3. To determine the charge of an element, you need to look at its electron configuration and determine the number of valence electrons.

3. The element with the largest electronegativity among the given options is Fluorine (F). Electronegativity generally increases across a period in the periodic table.

4. The element with the largest ionization energy in the given set is Zinc (Zn). Ionization energy generally increases across a period in the periodic table.

5. The mass number of an atom with 15 protons, 18 electrons, and 17 neutrons can be calculated by adding the number of protons and neutrons, which gives us a mass number of 32.
