Question

Which of the following is true about cations? Select 3 that apply

a
They have a - charge because valence electrons have been donated
b
they are smaller than the parent atom
c
they are made by non metals
d
they have a + charge because valence electrons have been donated
e
They are made by metal atoms

Answer 1

Correct answers: b, d, e.

- b (they are smaller than the parent atom): True — losing electrons reduces electron–electron repulsion and often removes an outer shell, so the ionic radius is smaller.
- d (they have a + charge because valence electrons have been donated): True — cations form by loss (donation) of electrons, giving a net positive charge.
- e (They are made by metal atoms): True — metals tend to lose electrons and form cations.
