Front

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into smaller parts, releasing a large amount of energy.

Front

What type of bond forms between two nonmetals?

Back

Covalent bond, which involves the sharing of electron pairs between atoms.

Front

Order the following particles by their ability to penetrate matter: Alpha, Beta, Gamma.

Back

Alpha particles have the least ability to penetrate matter, followed by Beta particles, and Gamma rays have the highest ability.

Front

What is the charge of an ion formed by an element that gains three electrons?

Back

The charge would be 3-.

Front

What does the octet rule state?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which an atomic nucleus emits an alpha particle, consisting of two protons and two neutrons.

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a beta particle (an electron or positron) is emitted from an atomic nucleus.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a sea of delocalized electrons.

Front

How do you determine the charge of a monatomic ion?

Back

The charge of a monatomic ion is determined by the number of electrons lost or gained compared to the neutral atom.
