Question

What is the atomic weight of an element if it has 7 protons, 7 electrons, and 6 neutrons?

Answer 1

The atomic weight of an element is determined by the combined mass of protons and neutrons in its nucleus. To find the atomic weight, we add the number of protons (7) and neutrons (6):

Atomic weight = number of protons + number of neutrons
Atomic weight = 7 protons + 6 neutrons
Atomic weight = 13

Therefore, the atomic weight of this element is 13.
