Gerry is looking at an unknown element. He knows it has 1 valence electron and is highly reactive with water. What group is the element most likely in? Group 1
Group 2
Group 17
Group 18

Group 1

because they have just one valance electron, group 1 elements are very reactiv.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.

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: )
