Ionic and covalent bonds

Front

What are ionic bonds?

Back

Ionic bonds are formed when one atom transfers electrons to another atom, resulting in the formation of positively and negatively charged ions that attract each other.

Front

What are covalent bonds?

Back

Covalent bonds are formed when two atoms share one or more pairs of electrons, allowing each atom to attain a full outer shell of electrons.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight electrons in their outermost shell, which makes them more stable.

How many valence electrons do elements in group 14 have?

Back

Elements in group 14 have 4 valence electrons.

Front

What type of bond forms between metals and nonmetals?

Back

Ionic bonds typically form between metals and nonmetals.

Front

What happens to atoms that form positive ions?

Back

Atoms that form positive ions tend to lose electrons.

Front

Is hydrogen a metal or a non-metal?

Back

Hydrogen is considered a non-metal.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of covalent bond where the electrons are shared unequally between the two atoms, resulting in a slight charge difference.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons and the attraction between charged ions, while covalent bonds involve the sharing of electrons between atoms.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.
