Chemical Bonding

Front

What is covalent bonding?

Back

Covalent bonding is a type of chemical bond that occurs when two nonmetals share electrons to achieve a full outer shell.

Front

What type of elements typically form covalent bonds?

Back

Covalent bonds typically form between nonmetals.

Front

What is an ionic bond?

Back

An ionic bond is a type of chemical bond that occurs when one atom transfers electrons to another atom, usually between metals and nonmetals.

Front

Which elements usually form negative ions?

Back

Nonmetals usually form negative ions.

Front

Which elements usually form positive ions?

Back

Metals usually form positive ions.

Front

What is a metallic bond?

Back

A metallic bond is a type of chemical bond that occurs between metal atoms, characterized by a 'sea of electrons' that are free to move.

Front

What is a Lewis dot diagram?

Back

A Lewis dot diagram is a representation of the valence electrons of an atom, shown as dots around the element's symbol.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is electronegativity?

Back

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

Front

What is the octet rule?

Back

The octet rule states that atoms tend to bond in such a way that they have eight electrons in their valence shell, achieving a stable electron configuration.
