All matter is made of _________.

• energy 

• atoms 

• electrons 

• compounds 

Answer explanation

All matter is made of atoms, which are the basic building blocks of matter. While energy, electrons, and compounds are related concepts, atoms are the fundamental units that compose all substances.

What is at the center of every atom?

• An electron

• A compound

• A molecule

• A nucleus

Answer explanation

The nucleus is at the center of every atom, containing protons and neutrons. Electrons orbit around the nucleus, while compounds and molecules are formed from atoms, not at their center.

The positively charged particles of an atom are the ________.

• electrons

• protons

• neutrons

• protons & neutrons

Answer explanation

The positively charged particles of an atom are the protons. Electrons are negatively charged, and neutrons have no charge. Therefore, protons are the correct answer.

What does the nucleus of an atom contain?

• Electrons and neutrons

• Protons and neutrons

• Neutrinos and positrons

• DNA and RN

Answer explanation

The nucleus of an atom contains protons and neutrons. Protons are positively charged, while neutrons have no charge. Electrons orbit the nucleus, and neutrinos and positrons are not found in the nucleus.

Atoms are made up of ________________

• energy

• electrons

• subatomic particles

• gasses

Answer explanation

Atoms are made up of subatomic particles, which include protons, neutrons, and electrons. While electrons are part of this structure, the broader category of subatomic particles encompasses all components of an atom.

The subatomic particles that make up an atom.

• solid, liquid, gas

• electrons, protons, nucleus

• energy, protons, nucleus

• electrons, protons, neutrons

Answer explanation

The correct answer is 'electrons, protons, neutrons' because these are the three main subatomic particles that compose an atom. Electrons are negatively charged, protons are positively charged, and neutrons are neutral.

__________ are negatively charged particles that are in the orbitals around the nucleus.

• protons

• nucleus

• neutrons

• electrons

Answer explanation

Electrons are negatively charged particles that orbit the nucleus of an atom. Protons are positively charged, neutrons are neutral, and the nucleus is the center of the atom, making electrons the correct answer.

A proton has a ___________ charge.

• positive

• negative

• neutral

• massive.

Answer explanation

A proton is a subatomic particle found in the nucleus of an atom and carries a positive charge. This distinguishes it from electrons, which have a negative charge, and neutrons, which are neutral.
