Please be I need this quick 2. For each pair of atoms determine which can steal an electron easier (higher electronegativity),
draw a picture of Bohr's model, and explain why:

a. Oxygen and Fluorine
b. Sodium and Potassium
c. Boron and Calcium

Option (A) is the correct answer.

Explanation:

An atom who has seven valence electrons in its ground state will have the following electronic configuration in its sub shells as 2, 7.

Thus, there will be in total 9 electrons and it is known that fluorine has atomic number 9.

Whereas sodium has 2, 8, 1 electrons in its sub-shell.

Calcium has 2, 8, 8, 2 electrons in its sub-shell and oxygen has 2, 6 electrons in its sub-shell.

Thus, we can conclude that out of the given options, fluorine is the element whose atom in the ground state has seven valence electrons.

i am going to put the answers in order i dint feel like typing it out so yeah

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
