Mr. adams asked his students to write the chemical symbols for the element zinc. he wrote the student's answers on the whiteboard. which answer is correct?

The chemical symbol of zinc element is Zn.

Explanation:

The chemical symbol of zinc element is 'Zn'.

Zinc is a metal belonging 3-d transition series metal with atomic number 30 and atomic mass of 65.38 g/mol. It has blue silvery appearances.

The electronic configuration of Zinc:

[tex\]Zn=[Ar]3d^{10}4s^2[/tex]

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
