Front

What is the electron configuration of Sulfur (S)?

Back

The electron configuration of Sulfur (S) is 1s² 2s² 2p⁶ 3s² 3p⁴.

Front

What is a valence electron?

Back

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

Front

How many valence electrons does a Strontium (Sr) atom have?

Back

Strontium (Sr) has 2 valence electrons.

Front

What happens to an atom with 3 valence electrons when it forms bonds?

Back

An atom with 3 valence electrons is likely to lose 3 electrons to achieve a stable octet.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to have a full outer shell of 8 electrons.

Front

What is the difference between a group and a period in the periodic table?

Back

A group is a column in the periodic table where elements have similar properties and the same number of valence electrons. A period is a row where elements have the same number of electron shells.

Front

Which element is likely to gain electrons to achieve a stable octet: Nitrogen or Strontium?

Back

Nitrogen is likely to gain electrons to achieve a stable octet, while Strontium is likely to lose electrons.

Front

What is a dot diagram?

Back

A dot diagram (or Lewis dot structure) represents the valence electrons of an atom as dots around the element's symbol.

Front

How many electrons does an atom of Carbon (C) need to gain or lose to achieve a stable octet?

Back

Carbon (C) needs to gain 4 electrons to achieve a stable octet.

Front

What is the significance of the periodic table's groups?

Back

Elements in the same group have similar chemical properties due to having the same number of valence electrons.
