Question

You have an atom with 3 protons ,4 neutrons ,and 3 electrons .adding a neutron will ...

Answer 1

Explanation:

Adding a neutron will not affect the charge. The atom remains neutrally charged.

Since the charge of a neutron is neutral, or 0, the charge is not affected. Protons have a positive charge, whereas electrons have a negative charge. Since there are an equal number of protons and electrons, they cancel out.

Adding a neutron also increases the mass by 1. The mass of a neutron is 1 amu. The atomic mass is calculated by protons + neutrons.

Originally, the mass is 7 (because 3+4). The mass would now be 8 (because 3+5).
