• Current

• Static

Which subatomic particles is/are positively charged?

• Protons only

• Protons and neutrons

• Electrons only

• Electrons and neutrons

Which subatomic particles is/are negatively charged?

• Protons only

• Protons and neutrons

• Electrons only

• Electrons and neutrons

Which subatomic particles is/are located in the nucleus of an atom?

• Protons only

• Protons and neutrons

• Electrons only

• Electrons and neutrons

Which subatomic particles is/are located around the nucleus of an atom?

• Protons only

• Protons and neutrons

• Electrons only

• Electrons and neutrons

Which subatomic particles can be moved to and from materials?

• Protons only

• Protons and neutrons

• Electrons only

• Electrons and neutrons

• Electrons and protons

Answer explanation

Since they aren't stuck in the nucleus, electrons can move from one object to another.

How can an object become negatively charged?

• Only by gaining electrons

• Only by losing electrons

• Only by losing protons

• Either by losing protons or gaining electrons

Answer explanation

Only the electrons are free to move from one object to another.

How can an object become positively charged?

• Only by gaining electrons

• Only by losing electrons

• Only by losing protons

• Either by losing protons or gaining electrons

Answer explanation

Only the electrons are free to move from one object to another.

Some rabbit fur is rubbed on some pvc pipe. As a result, the pvc pipe becomes negatively charged. Which statement is true?

• The pvc lost protons to the fur so the fur became positively charged

• The pvc lost electrons to the fur so the fur became positively charged

• The pvc took electrons from the fur so the fur became positively charged

• The fur took protons from the pvc so the fur became positively charged

Answer explanation

Only the electrons are free to move from one object to another.

If something gains electrons, it becomes more negative. If something loses electrons, it becomes more positive.
