Question

if an element has 5 protons and 6 neutrons... what is its atomic mass? *
5
6
11
1

Explanation:

Step1: Recall atomic mass formula

Atomic mass (approximate) is the sum of protons and neutrons. Formula: $Atomic\ mass = Number\ of\ protons + Number\ of\ neutrons$

Step2: Substitute values

Given protons = 5, neutrons = 6. So, $Atomic\ mass = 5 + 6 = 11$

Answer:

11 (corresponding to the option with 11)
