Is sodium an element in Group 2?

Is sodium an element in Group 2?

sodium (Na), chemical element of the alkali metal group (Group 1 [Ia]) of the periodic table. Sodium is a very soft silvery-white metal.

What is family 2 on the periodic table?

Group 2A (or IIA) of the periodic table are the alkaline earth metals: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

What family group is sodium in?

the alkali metals
It is one of the highly reactive group one elements that are named the alkali metals.

What family of elements is Group 2?

alkaline-earth metal
alkaline-earth metal, any of the six chemical elements that comprise Group 2 (IIa) of the periodic table. The elements are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Which of these is an element of Group 2?

The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).

Why is group 2 called alkaline earth metals?

Solution : Group 2 elements except beryllium are known as alkaline earth metals. These are so called because their oxides and hydroxides are alkaline in nature and these metal oxides are found in Earth. s crust.

Why is sodium a group 1 element?

Atoms of group 1 elements all have one electron in their outer shell. This means that the alkali metals all have similar chemical properties . When a group 1 element takes part in a reaction, its atoms each lose one electron. This forms positively charged ions .

What are families on the periodic table?

On the periodic table, there are families which are groups of elements with similar properties. These families are alkali metals, alkaline earth metals, transition metals, post-transition metals, metalloids, halogens, noble metals, and noble gases. Many of these families belong to a single group on the periodic table.

Is sodium an alkali metal?

Group 1A (or IA) of the periodic table are the alkali metals: hydrogen (H), lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

What element is in Group 2 Period 4?

a. The given element is calcium. The atomic number of calcium is 20.

Is Group 2 metal or nonmetal?

Group 2 elements are classified as metals. Group 2 elements are also known as alkaline earth metals.

Which of these is an element of group 2?

What is the name of Group 2 on the periodic table?

alkaline earth metals
Group 2 of elements on the periodic table refers to alkaline earth metals. They are beryllium, magnesium, calcium, strontium, barium, and radium.

Which element is found in Group 2 and Period 3?

magnesium
Hence the name of the element is magnesium.

What charge does group 2 have?

+2 charge
Thus, the group 2 metals tend to have a +2 charge. On the other side of the periodic table elements gain electrons to resemble the next higher noble gas.

What is the reactivity of group 2?

The Group 2 metals become more reactive towards water as you go down the Group. There is an additional reason for the lack of reactivity of beryllium compared with the rest of the Group. Beryllium has a strong resistant layer of oxide on its surface which lowers its reactivity at ordinary temperatures.
