The following electron configurations represent excited states. Identify the element, and write its ground-state condensed electron configuration

**Answer 1**

1s^2, 2s^2, 3p^2, 4p^1

it has 7 electrons showing (2+2+2+1 = 7)….. that’s nitrogen

its ground state configuration…………1s^2, 2s^2, 2p^3

its ground state condensed configuration……[He], 2s^2, 2p^3

[Ar] , 3d^10, 4s^1, 4p^4, 5s^1

it has 34 electrons showing, …………….that’s Selenium

ground state configuration……………. [Ar] , 3d^10, 4s^2, 4p^4,

[Kr] , 4d^6, 5s^2, 5p^1

it has 45 electrtons showing…………….that’s Rhodium

ground state configuration…………….[Kr] , 4d^7, 5s^2,
