Question

question 3 (1 point) build a lithium atom with the following symbol and fill in the table below it. notice this lithium has a mass of 5 and an atomic number of 3 (3 protons). name lithium - 5 number of protons ______ number of neutrons ______ mass 5 natural abundance 0 % stable? unstable blank 1: blank 2:

Explanation:

Step1: Recall atomic number definition

The atomic number is equal to the number of protons. Given atomic number of lithium - 5 is 3, so the number of protons is 3.

Step2: Calculate number of neutrons

The mass number is the sum of protons and neutrons. Mass number = 5, number of protons = 3. So number of neutrons = Mass number - Number of protons = 5 - 3=2.

Answer:

Blank 1: 3
Blank 2: 2
