Problem 7Q

Is matter usually charge-neutral? How would matter be different if it were not charge-neutral?

Step-by-Step Solution:
Step 1 of 3

Solution 7Q

Matter is composed of atom and atom has equal number of protons and electrons. On the other hand, protons are positively charged and electrons are negatively charged. Therefore, matter is composed of equal number of positively and negatively charged which cancel out each other and resulting charge is equal to zero. Thus matter is neutrally charged.

Charge of Proton = 1+

Charge of electron =1-

Thus matter of resulting charge = -1+1 = 0

By changing the number of electrons will change the neutrality of an atom. Thus. it will change the chemical or physical properties of an atom. The number of protons always remain same in an atom. The charge neutrality is dependent on the number of electrons.

For example : X + e -----> X-

X - e -----> X+

When an electron is removed from an atom, it gains positively charged.this is because no of proton will be more than number of electron.

On the other hand, when an electron is added to the core atom,  it gains negatively charged.This is because no of protons will be less than number of electrons.

Therefore, both the charged matter will have different physical or chemical properties.
