Question

Identify the missing numbers for Vanadium (V) for "A, ""B," and "C" in the chart below. The first number in the answer selection represents "A", the second number in the answer selection represents "B," and the third number in the answer selection represents "C."

Answer 1

Answer:

The right choice is:

B. 21, 21, 53.

Explanation:

Atomic Number = Number of electrons = Number of protons

So, the No. of protons (A) =  Number of electrons =21

Atomic Number (B) = Number  of electrons =21

Mass number (C) = Number of electrons + Number of neutrons = 21 + 32 = 53

So, the right choice is:

B. 21, 21, 53.
