What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons in order to have eight valence electrons, achieving a stable electron configuration similar to that of noble gases.

How does calcium obey the octet rule?

Back

Calcium obeys the octet rule by giving up two electrons, resulting in a stable electron configuration.

Front

What characteristic of metals makes them good electrical conductors?

Back

Metals are good electrical conductors because they have mobile valence electrons that can move freely, allowing electric current to flow.

Front

How many valence electrons does a helium atom have?

Back

A helium atom has 2 valence electrons.

Front

How many valence electrons are in an atom of arsenic?

Back

An atom of arsenic has 5 valence electrons.

Front

What is a dot diagram?

Back

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

Front

What is the significance of valence electrons in chemical bonding?

Back

Valence electrons are crucial in chemical bonding as they are the electrons involved in forming bonds between atoms.

Front

What happens to the valence electrons of metals during bonding?

Back

In metals, valence electrons are delocalized and can move freely, which allows them to conduct electricity and heat.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.

Front

What is the electron configuration of calcium?

Back

The electron configuration of calcium is 1s² 2s² 2p⁶ 3s².
