Question

What is the charge on the subatomic particles represented in Figure 4-3? Assuming all the

particles in the nucleus are visible, what are the atomic and mass numbers of the atom shown?
(4 points) **extended response please?**

Answer 1

proton charge: positive

neutron charge: neutral (no charge)

Atomic number: 8

Mass number: 17

Step-by-step explanation:

The charge of the subatomic particles represented in Figure 4-3 are:

proton: positive

neutron: neutral (no charge)

Atomic number: number of protons in the nucleus.

Atomic number: 8

Mass number: number of protons and neutrons in the nucleus.

Mass number: 9 neutrons + 8 protons = 17

Answer 2

Atomic number is 8 and mass number is 17.

Step-by-step explanation:

From the figure,

The number of protons= 8

The number of neutrons = 9

Any atom contains equal number of protons and electrons.Hence, the atomic number of element is 8.

The atomic number eight element in the periodic table is "Oxygen.

And mass number is 17.
