That would be 25,270.7904 miles
M(Mn(ClO3)3)=(54.938)+(35.45x3)+(15.999x9)
M(Mn(ClO3)3)=305.279 g/mol
<span>The question is asking for the number of valence electron that are available fo bonding in bromine. Bromine belongs the group 7 of the periodic table, thus it has seven electrons in its outermost shell. At times, all these seven valence electrons can be involved in a chemical bonding in order to form an octet structure. Also, bromine can form a single covalent bond with other elements during chemical reactions. </span>
<em>Answer:</em>
- The atom have a full valence electron shell.
<em>Explanation:</em>
- My question is that why covalent bonds take place?
Every atoms tends to from bond with another atoms in order to get nearest electronic configuration of nobel gases. They become stable when their valence shell become complete. So when covelant bond forms between atoms, share electrons to each other and stabilize themselves.
