Q

Why don’t covalent bonds conduct electricity?

A

Because there are no charged particles free to move

27
Q

What are the subatomic particles found in an atom?

A

PNE

28
Q

Define charged particle.

A

Charged particle is a particle that has an electric charge.

29
Q

What are the charged particles found in an atom?

A

Electrons and protons are the charged particles found in an atom.

30
Q

What are the different types of charged particles?

A

Charged particles are of two types: positive charges and negative charges.

32
Q

What is the mass of a proton?

A

The mass of a proton is 1.672 × 10-27kilograms.

33
Q

Define atomic number.

A

The total number of protons in the nucleus of an atom is called atomic number.

34
Q

Define neutron number.

A

The total number of neutrons in the nucleus of an atom is called neutron number.

35
Q

Define mass number.

A

Mass number is the total number of protons and neutrons in the nucleus of an atom.
Mass number can be mathematically written as
A = Z + N
Where,
A = mass number
Z = atomic number
N = neutron number

36
Q

What happens when two opposite charges (One proton and one electron) are placed close to each other?

A

They get attracted.

37
Q

Which force causes electrons and protons to experience an attractive or repulsive force from each other?

A

Electrostatic force causes electrons and protons to experience an attractive and repulsive force from each other.

38
Q

Which force binds the protons and neutrons together to form a nucleus?

A

The strong nuclear force between the protons and neutrons binds them together to form a nucleus.
