Question

In an atom, electrons have a negative charge and protons have a positive charge. One negative and

one positive cancel each other, just like zero pairs. An atom has 354 electrons and 139 protons.
What is the amount and type of charge?

Answer 1

So

• Electrons=-354
• Protons=+139

Net charge

• 354-139
• -215

Negative charge and the amount is 215

Answer 2

The charge is negative and the amount is 215

Explanation:

Electrons are negative

-354

Protons are positive

+139

-354+139

-215
