Chemical Bonding Flashcard

Front

When an atom gains an electron, what charge does it acquire?

Back

Negatively charged.

Front

What forms covalent bonds in chemical compounds?

Back

Pairs of electrons are shared between two nonmetal atoms.

Front

Define a diatomic molecule.

Back

A molecule consisting of two atoms of the same element.

Front

If an oxygen atom has 8 protons and 10 electrons, what is its charge?

Back

O²⁻.

Front

What type of bond is formed by sulfur (S) and bromine (Br) based on electronegativities?

Back

Non-polar covalent.

Front

What is an ionic bond?

Back

A bond formed when electrons are completely transferred from one atom to another.

Front

What is electronegativity?

Back

The tendency of an atom to attract electrons in a chemical bond.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while non-polar covalent bonds have equal sharing.

Front

What is a cation?

Back

A positively charged ion formed when an atom loses electrons.

Front

What is an anion?

Back

A negatively charged ion formed when an atom gains electrons.
