Question

How many valence electrons does cesium have
a) 1
b) 2
c) 6
d) 7

Answer 1

Cesium has one valence electron, as it belongs to group 1 of the periodic table.

Step-by-step explanation:

Cesium (Cs) has one valence electron. This can be deduced from its position in group 1 (also known as the alkali metals) of the periodic table, which consists of elements with a single electron in their outermost shell, thus having one valence electron. This means that for the question on how many valence electrons cesium has, the correct answer is a) 1.
