Question

Which of the following correctly lists the name of the element, the symbol for the ion, and the name of the ion?

A. fluorine, F+, fluoride ion
B. zinc, Zn2+, zincate ion
C. copper, Cu+, cuprous ion
D. barium, Ba3+, barium ion

Answer 1

The correct answer is B.

Hope this helps you.

Answer 2

zinc, Zn²⁺, zincate ion

Step-by-step explanation:

Let us check with all the given examples:

a) Fluorine (F). It is the most electronegative element and thus cannot form positive ion. It will gain electron and form a negative ion (F⁻) known as Fluoride ion.

b) Zinc: it is a metal and give two electrons easily to attain noble gas configuration. Hence it will form Zincate ion (Zn⁺²).

c) Copper,: it is a metal and can form positive ion easily.

It can give either two or one electron to form

Cu⁺²: Cupric ion [More common]

Cu⁺: Cuprous ion

d) Barium : it is alkaline earth metal and will give only two electron to form dipositive ion barium ion (Ba⁺²)
