what is the group and period of an element with an electronic configuration 1s 2s2 2p6​

Sagot :

Answer:

The superscript '2' tells us that the element is found in the 2nd column of the p-block Group 14.

Explanation:

The supercripts (2, 2, 6, 2 and 2) are the number of electrons in each orbital. Simply add up these numbers, which will give you 14.

Now just look for the element on the periodic table with the atomic number of 14.

This is because the atomic number tells you the number of protons, and the number of electrons is equal to that of the protons (unless the element has become an ion, of course, but since there is no information saying it is an ion, we'll assume it isn't).

So, the element with the atomic number of 14 is Silicon!
