Front

What are alkali metals?

Back

Alkali metals are elements in Group 1 of the periodic table, known for being highly reactive, especially with water, and typically have one electron in their outermost shell.

Front

What is the reactivity of alkali metals?

Back

Alkali metals are highly reactive due to their single valence electron, which they readily lose to form positive ions.

Front

What is the correct formula for Lithium dichromate?

Back

Li₂Cr₂O₇

Front

What do positive ions tend to do?

Back

Positive ions tend to donate electrons.

Front

What is the name of the compound NO?

Back

Nitrogen monoxide.

Front

What is a Lewis Dot Diagram?

Back

A Lewis Dot Diagram is a representation of the valence electrons of an atom, showing how they are arranged in bonds with other atoms.

Front

What is the general trend in boiling points of alkali metals?

Back

Alkali metals generally have low boiling points that decrease down the group.

Front

What is the significance of the octet rule in chemistry?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to greater stability.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.

Front

What is the charge of a sodium ion (Na⁺)?

Back

The charge of a sodium ion (Na⁺) is +1.
