Question

directions: complete the following table.

atomic structure	protons (p⁺)	neutrons (n⁰)	electrons (e⁻)
location in atom
charge
mass (u)

Explanation:

Step1: Recall proton properties

Protons are in the nucleus, have a charge of + 1, and a mass of approximately 1 u.

Step2: Recall neutron properties

Neutrons are in the nucleus, have no charge (charge of 0), and a mass of approximately 1 u.

Step3: Recall electron properties

Electrons are outside the nucleus, have a charge of - 1, and a mass of approximately 0.00055 u (very small compared to protons and neutrons).

Answer:

Atomic Structure	Protons ($p^+$)	Neutrons ($n^0$)	Electrons ($e^-$)
Charge	+1	0	- 1
Mass (u)	1	1	0.00055
