Question

identify the element, the mass, and the charge.

1. p = 37 e = 36 n = 48 element - mass - charge -
2. p = 8 e = 10 n = 7 element - mass - charge -

Explanation:

Step1: Identify element by protons

The number of protons (p) determines the element. Use periodic table.

Step2: Calculate mass number

Mass number = p + n.

Step3: Determine charge

Charge = p - e.

Answer:

1. Element: Rubidium (Rb), Mass: 85, Charge: +1
2. Element: Oxygen (O), Mass: 15, Charge: -2
