Question

10 formula 1 point an atom has 8 protons, 8 electrons, and 8 neutrons. what is the atomic mass of the atom? answer 11 formula 1 point if an element has 8 number of protons, 10 number of neutrons, and 7 number of electrons, what is the atomic mass of answer

Explanation:

Step1: Recall atomic - mass formula

Atomic mass = number of protons + number of neutrons. Electrons' mass is negligible.

Step2: Calculate for first atom

For the atom with 8 protons and 8 neutrons, atomic mass = 8 + 8 = 16.

Step3: Calculate for second atom

For the element with 8 protons and 10 neutrons, atomic mass = 8+10 = 18.

Answer:

1. 16
2. 18
