Covalent and Ionic Bonding Concepts

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

How many valence electrons does Strontium have?

Back

Strontium has 2 valence electrons.

Front

What is the tendency of Aluminum in terms of electron loss?

Back

Aluminum tends to lose 3 electrons.

Front

What types of bonds hold elements together to form molecules and compounds?

Back

Covalent and ionic bonds.

Front

How are covalent bonds formed?

Back

Covalent bonds are formed by the sharing of electrons between atoms.

Front

What is an ionic bond?

Back

An ionic bond is formed when one atom transfers electrons to another atom, resulting in the attraction between positively and negatively charged ions.

Front

What is the difference between covalent and ionic bonding?

Back

Covalent bonding involves sharing electrons, while ionic bonding involves the transfer of 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 8 electrons.

Front

What is a molecule?

Back

A molecule is a group of two or more atoms bonded together, which can be either covalent or ionic.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.
