Protons and neutrons are held together inside the nucleus.
Explanation:
The strongest force in the universe is the nuclear forces holding the neuclons together in an atom.
This force is referred to as the strong nuclear forces. It is by far stronger than electromagnetic forces.
Nuclear forces are stronger than chemical binding forces which is seen between two particles attracting one another via static electricity.
It stronger than the gravitational force experienced by two equal masses that falls to the ground at the same speed.

Answer:
Option B
Explanation:
A gaseous, highly reactive non-metal
as per the question charlie runs to the store which is 4 km away
hence the total distance covered [S] is 4 km
he takes 30 minutes to reach the store.
hence the total time taken [t] = 30 minutes=0.5 hour
We have to calculate the average speed.
the average speed[v]=
=
=8 km/hour
then we have to calculate the total distance traveled by charlie in 1 hour.
the distance covered S=
=8 km/hour ×1 hour
=8 km
Hence the average speed of charlie is 8 km/hour and he covers a distance of 8 km in 1 hour.
<h3><u>Answer;</u></h3>
They are anions.
<h3><u>Explanation</u>;</h3>
- Polyatomic ions are the ions that contain 2 or more different atoms that are covalently bonded to each other.
- Examples include; Nitrate : NO₃⁻, Sulfate : SO₄²⁻,Hydroxide : OH⁻, and Phosphate : PO₄³⁻, etc.
- Polyatomic ions are tightly bound group of atoms that has a positive or negative charge and behaves as a unit.
