Question

1. (multiple choice) ions a through c above (from question #25) are all ______ while ions d through f are all ______.

a) anions, cations
b) cations, containing more protons than electrons
c) anions, containing more electrons than protons
d) containing more protons than electrons, containing more electrons than protons

1. predict whether each of the following elements would be more likely to form a cation or anion, will it gain or lose electrons, and how many electrons will it gain or lose?

a) na
b) ca
c) si
d) n
e) fe
f) co
g) k
h) p
i) o
j) f
k) ti
l) br
m) li
n) h
o) c

Explanation:

(Question 26):

Step1: Define cations/anions

Cations have more protons than electrons; anions have more electrons than protons.

Step2: Analyze option consistency

Standard ion sets: a-c are cations (more protons), d-f are anions (more electrons). Option d matches this.

(Question 27):
Uses octet rule: metals lose electrons to form cations; nonmetals gain electrons to form anions; transition metals lose variable electrons.

Answer:

(Question 26):
d) containing more protons than electrons, containing more electrons than protons
