Chemical Bonding Review

Front

How do covalent bonds form?

Back

Atoms share electrons to fill their valence shell.

Front

What best describes valence electrons?

Back

Electrons in the outer-most shell.

Front

How many valence electrons do elements in Group 1, the Alkali Metals, have?

Back

1

Front

Which part of the atom is responsible for chemical bonding?

Back

Outer/Valence Electrons.

Front

Why do Hydrogen and Helium only need two valence electrons?

Back

The first electron shell can only hold two electrons.

Front

What is a covalent bond?

Back

A chemical bond formed when two atoms share one or more pairs of electrons.

Front

What is the octet rule?

Back

Atoms tend to bond in such a way that they have eight electrons in their valence shell.

Front

What are ionic bonds?

Back

Chemical bonds formed through the transfer of electrons from one atom to another.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve electron transfer, while covalent bonds involve electron sharing.

Front

What are the properties of covalent compounds?

Back

They typically have lower melting and boiling points and do not conduct electricity.
