Question

Name the 1st and 2nd groups on the periodic table
for example calcium and magnesium

Answer 1

The 1st group on the periodic table is called the alkali metals, and the 2nd group is called the alkaline earth metals.

Step-by-step explanation:

The 1st group on the periodic table is called the alkali metals and includes elements like lithium, sodium, and potassium. These elements are highly reactive and easily lose their outermost electron to form a +1 ion. They are soft and have low melting points.

The 2nd group on the periodic table is called the alkaline earth metals and includes elements like beryllium, magnesium, and calcium. These elements are less reactive than the alkali metals but still reactive enough to readily lose two electrons to form a +2 ion. They are harder and have higher melting points compared to the alkali metals.
