Question

t below, identify the amount of each subatomic particle. 3 li lithium 6.94 8 o oxygen 15.99 protons: 3 protons: neutrons: neutrons: electrons: electrons:

Explanation:

Step1: Recall atomic number property

The atomic number is equal to the number of protons and electrons in a neutral atom. For Li, atomic number is 3, so protons = 3 and electrons = 3. For O, atomic number is 8, so protons = 8 and electrons = 8.

Step2: Calculate number of neutrons

The mass - number (approximate whole - number value from the atomic mass) is the sum of protons and neutrons. For Li, mass number is 7 (approx. from 6.94), so neutrons = 7 - 3=4. For O, mass number is 16 (approx. from 15.99), so neutrons = 16 - 8 = 8.

Answer:

For Lithium (Li):
Protons: 3
Neutrons: 4
Electrons: 3
For Oxygen (O):
Protons: 8
Neutrons: 8
Electrons: 8
