Solution: Vanadium can have multiple ions. When vanadium has this symbol: 51V5+ The atomic number (Z), mass number (A), number of neurons (n) and number of electrons (e) are: a. Z = 23, A = 51, n = 28, e = 18 b. Z = 51, A = 23, n = 28, e = 23 c. Z = 28, A = 51, n = 28, e = 23 d. Z = 28, A = 23, n = 51, e = 18

Problem

Vanadium can have multiple ions. When vanadium has this symbol:

51V5+

The atomic number (Z), mass number (A), number of neurons (n) and number of electrons (e) are:

a. Z = 23, A = 51, n = 28, e = 18

b. Z = 51, A = 23, n = 28, e = 23

c. Z = 28, A = 51, n = 28, e = 23

d. Z = 28, A = 23, n = 51, e = 18
