Give the symbol for the element that has an electron configuration of 1s22s22p63s23p4.

The symbol for the given element is S.

Explanation:-

Sulphur is an element with atomic number 16 and thus contain 16 electrons. It is a p block element as the last electron enters the p orbital. The nearest noble gas is Neon with 10 electrons.

The electrons are filled according to Afbau's rule in order of increasing energies and thus the electronic configuration is:  

The electronic configuration of sulphur in terms of noble gas is :

air quality

poor drinking water

and heavy polution

can lead to poor health

the answer would be a
