Question

Which part of helium atom is positively charged

Answer 1

Protons and neutrons of an atom together makes nucleus of an atom.This is the part where helium atom has positive charge.

Step-by-step explanation:

In an atom there are three subatomic particles which are :

1. Electrons : These are negatively subatomic particles located inside the atoms but outside of the nucleus.

2. Protons : These are positively subatomic particles located inside the atoms in the nucleus.

3. Neutrons : These are subatomic particles with no charge located inside the atoms in the nucleus.

Protons and neutrons of an atom together makes nucleus of an atom.This is the part where atoms has positive charge.

Mass of the atom = P(protons) +N(neutrons )

Atomic number = Number of protons (P)

Helium has atomic number of 2. Which means that it has 2 protons in its nucleus.

Protons and neutrons of an atom together makes nucleus of an atom.This is the part where helium atom has positive charge.

Mass of the atom = P(protons) +N(neutrons )

Answer 2

A helium atom has a neutral charge where its oxidation number is 0. Neutrons essentially ha no charge. Protons are positively charged while the electrons are negatively charged. The number of protons and electrons are equal which gives a neutral charge for this atom.
