Atoms, ions and static electricity

Front

What is the atomic number of an element?

Back

The atomic number is the value that represents the number of protons in an element.

Front

How is the identity of an element determined?

Back

The identity of an element is determined by the number of protons it has.

Front

What do all atoms of the same element have in common?

Back

All atoms of the same element have the same number of protons.

Front

What happens when two like charges interact?

Back

If two charges repel each other, the two charges must be negative and negative.

Front

What occurs to a magnesium atom to become an ion?

Back

A magnesium atom becomes an ion by losing electrons.

Front

Define an ion.

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What are protons?

Back

Protons are positively charged particles found in the nucleus of an atom.

Front

What are neutrons?

Back

Neutrons are neutral particles found in the nucleus of an atom, contributing to the mass but not the charge.

Front

What are electrons?

Back

Electrons are negatively charged particles that orbit the nucleus of an atom.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, which can cause them to attract or repel each other.
