a unknown substance A on a chemical action decomposed to B and C . what type of substance are A, B and C - an element , a compound or a mixture ? justify your answer

I HOPE it will help you

Explanation:

A =element

B=compound

8

explanation:

each principal energy level above the first contains one s orbital and three p orbitals. a set of three p orbitals, called the p sublevel, can hold a maximum of six electrons. therefore, the second level can contain a maximum of eight electrons - that is, two in the s orbital and 6 in the three p orbitals.

mark brainliest and have a great day!

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of c is as shown here in the image.
