Question

question 6 (1 point) if an atom has 3 protons, 4 neutrons, and 3 electrons, what would its mass be?
○ a 3
○ b 4
○ c 7
○ d 10

Explanation:

Step1: Recall atomic mass formula

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

Step2: Substitute values

Given protons = 3, neutrons = 4. So, $Atomic\ mass = 3 + 4 = 7$

Answer:

c. 7
