parts of Group 1 metals
These are a strange group of metals.
They are certainly not typical of the metals
we see every day.
Look at the photo opposite:
The group 1 metals:
are soft (they can be cut with a knife)
are not dense (lithium, sodium and potassium actually float on wate
have to be stored under oil.

Answer:
hydrogen
(Like the other elements in Group 1, hydrogen (H) has one electron in its outermost shell, but it is not classed as an alkali metal since it is not a metal but a gas at room temperature.) Brush up on the periodic table of elements.
Answer:
The alkali metals consist of the chemical elements lithium (Li), sodium (Na), potassium (K),[note 1] rubidium (Rb), caesium (Cs),[note 2] and francium (Fr). Together with hydrogen they constitute group 1,[note 3] which lies in the s-block of the periodic table. All alkali metals have their outermost electron in an s-orbital: this shared electron configuration results in their having very similar characteristic properties.[note 4] Indeed, the alkali metals provide the best example of group trends in properties in the periodic table, with elements exhibiting well-characterised homologous behaviour. This family of elements is also known as the lithium family after its leading element.
