Question

electronic configuration of alkali and alkaline earth metal respect to nobel gas​

Answer 1

Answer:

• The general form for the electron configuration of each alkali metal is ns1, where the n refers to the highest occupied principal energy level. For example, the electron configuration of lithium (Li), the alkali metal of Period 2, is 1s22s1.

Answer 2

Answer:

The elements in Group 2 (beryllium, magnesium, calcium, strontium, barium, and radium) are called the alkaline earth metals (see Figure below). These elements have two valence electrons, both of which reside in the outermost s sublevel. The general electron configuration of all alkaline earth metals is ns2.

All noble gases have general electronic configuration ns^2 np^6 except helium which has 1s^2.
