The electron configuration of an element is shown below. 1s^2 2s^2 2p^6 3s^2 3p^6

Based on the electron configuration, write one chemical property of this element.

It is a noble gas

Explanation:

It can form some compounds under various extreme conditions

this is Ar, a noble gas, a gas at STP and are basically has little chemical reactivity,

aplanation

:he electron configuration of an element is shown below.

1s^2 2s^2 2p^6 3s^2 3p^6

Based on the electron configuration, write one chemical property of this element.

all of the s an p orbitals ae filled, so this is a noble gas  with atomic # =

2 + 2 + 6 + 2 + 6 = 18 so

this ie element #18 and is Argon,Ar

all noble gases are gases at STP and are basically hae little chemical reactivity,a

the answer is a

photosynthesis

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
