What charge do electrons have in relation to protons?

Back

Electrons have an opposite charge to protons.

Front

If an atom is the size of a stadium, what would the nucleus be comparable to?

Back

The nucleus would be comparable to the size of a marble on the middle of the field.

Front

What is the relationship between electrons in the electron cloud?

Back

Electrons repel each other but are attracted to the protons in the nucleus.

Front

Why are atoms on the right side of the periodic table smaller?

Back

Atoms on the right side are smaller because they have more protons, which exert a stronger pull on the electrons, pulling them in closer.

Front

Which nucleus exerts a stronger attractive force: one with 11 protons or one with 18 protons?

Back

The nucleus with 18 protons exerts a stronger attractive force and pulls its electrons closer.

Front

What is the role of protons in the nucleus?

Back

Protons exert a positive charge that attracts negatively charged electrons.

Front

How does the number of protons affect atomic size?

Back

More protons in the nucleus lead to a stronger positive charge, pulling electrons closer and resulting in a smaller atomic size.

Front

What is the electron cloud?

Back

The electron cloud is the region around the nucleus where electrons are likely to be found.

Front

What happens to electrons when they are attracted to protons?

Back

Electrons move closer to the nucleus due to the attractive force of protons.

Front

What is the significance of the electron cloud model?

Back

The electron cloud model helps visualize the probable locations of electrons around the nucleus.
