Question

atomic # =
atomic mass =

of protons =

of neutrons =

of electrons =

Explanation:

Step1: Determine atomic number

The atomic number is the number at the top of the element box. So, Atomic # = 1.

Step2: Determine atomic mass

The atomic mass is the number at the bottom of the element box. So, Atomic Mass = 1.008.

Step3: Determine number of protons

The number of protons is equal to the atomic number. So, # of Protons = 1.

Step4: Determine number of neutrons

Neutrons = Atomic Mass (rounded to whole number) - Protons. Rounding 1.008 to 1. So, 1 - 1 = 0. # of Neutrons = 0.

Step5: Determine number of electrons

For a neutral atom, electrons = protons. So, # of Electrons = 1.

Answer:

Atomic # = 1
Atomic Mass = 1.008

of Protons = 1

of Neutrons = 0

of Electrons = 1
