Question 23

Question

When we write nuclear reactions, you use the A-Z-X formatting. Match the symbols to the terms they represent.

Column A
1.
A:
A
2.
Z:
Z
3.
X:
X
Column B
a.Atomic Number
b.Atomic Symbol
c.Atomic Mass

Answer 1

In nuclear reactions, the A-Z-X notation represents the following:

• A: Atomic Mass (the total number of protons and neutrons in the nucleus)
• Z: Atomic Number (the number of protons in the nucleus)
• X: Atomic Symbol (the chemical symbol of the element)

So the matches are:

1. A: c. Atomic Mass
2. Z: a. Atomic Number
3. X: b. Atomic Symbol
