Chemical Bonding and Properties

Front

What type of bond is formed between potassium (K) and bromine (Br)?

Back

Ionic bond: This bond is formed when one atom donates an electron to another, resulting in the formation of charged ions.

Front

What type of bond is present in ammonia (NH3)?

Back

Covalent bond: This bond is formed when two atoms share electrons.

Front

What is the result when an atom gains an electron?

Back

It becomes an anion: An anion is a negatively charged ion formed when an atom gains one or more electrons.

Front

Which element has the electron dot diagram that represents four valence electrons?

Back

Silicon: Silicon has four valence electrons, which allows it to form covalent bonds.

Front

What do atoms with few valence electrons (1-3) tend to do?

Back

They tend to lose them: Atoms with fewer valence electrons typically lose them to achieve a stable electron configuration.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when electrons are transferred from one atom to another, resulting in the formation of ions.

Front

What is a cation?

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.

Front

What is the octet rule?

Back

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