Answer: Two chlorine atoms
Explanation:
Chlorine is a nonmetal belonging to group 7 of the periodic table. It has an atomic number of 17 distributed as (2, 8, 7), so it has 7 valence electrons and needs JUST ONE to complete its outermost shell.
Cl + e- ---> Cl-
On the other hand, barium is a metal belonging to group 2 on the periodic table. It has an atomic number of 56 with 2
valence electrons in its outermost shell, and gives off the two electrons to form a stable octet structure.
Ba ----> Ba2+ + 2e-
Thus, barium loses its 2 outermost electrons to form a Ba2+ ion, while TWO chlorine atoms receive them to form 2Cl- resulting in an ionic bond in the compound, BaCl2 (Barium Chloride)
Ba2+ + 2Cl- ---> BaCl2
Balanced chemical reaction (dissociation) of <span>an aqueous solution of hypochlorous acid:

You're welcome bro, sorry for the late answer
Answer: option d
Explanation:
Project teams must be proactive. Each member of the team should empowered and each member can share ideas and experience in order to make the WBS more precise.
Answer:
The reactivity of Group 7 elements decreases down the group. ... The electrons in the outer shell move further away from the nucleus as we go down the group and the attraction force between the electrons and the nucleus become weaker and weaker. This weaker attraction in the larger atoms makes it harder to gain electron.
