Question

1. look at the model below. fill in the table below based on the atom in the model. note: coloring matches simulation (protons = pink, neutrons = gray, electrons = blue) (2 points) element protons neutrons electrons mass number charge

Explanation:

Step1: Count Protons

Protons are pink (orange in the diagram) with + charge. Count: 3.

Step2: Count Neutrons

Neutrons are gray. Count: 4.

Step3: Count Electrons

Electrons are blue with - charge. Count: 2.

Step4: Mass Number

Mass number = protons + neutrons = \( 3 + 4 = 7 \).

Step5: Charge

Charge = protons - electrons = \( 3 - 2 = +1 \).

Step6: Identify Element

Element with 3 protons is Lithium (Li).

Answer:

Element	Protons	Neutrons	Electrons	Mass Number	Charge
