An uncharged atom has six electrons. the nucleus of this atom must contain protons.
a. seven
b. five
c. six
d. eight

Answer : The correct option is, (C) six

Explanation :

There are three types of subatomic particles.

1) Protons

2) Neutrons

3) Electrons

Protons and neutrons are present inside the center of the nucleus and electrons are present outside the nucleus.

As we know that in the neutral atom, the number of electrons is equal to the number of protons.

The number of neutrons = Atomic mass - Number of protons

If an uncharged atom has six electrons then the nucleus of this atom must contain six protons.

Hence, the correct option is, (C) six
