4d5 5s1 is where electron configurations of outer sublevels is the most stable. <span>this could be a tricky question because of the fact the respond is going against the final rule that could say that 4d4 5s2 is the main sturdy. the final 2 a merely nonsence there is not any such factor as s3 or s4</span>
Answer:
opg
Explanation:
A series of chemical reactions transform Volatile Organic Compounds (VOCs) into substances that combine with nitrogen dioxide to produce PAN (Peroxyacytyl nitrate), yet another element in smog. Nitrogen dioxide in the air also reacts with water vapor to form nitric acid, one of the types of acid in acid rain.
Answer:Ethyne
Explanation:
Ethyne is more commonly known under the trivial name acetylene. It is the simplest of the alkynes, consisting of two carbon atoms connected by a triple bond, leaving each carbon able to bond to one hydrogen atom. Since both carbon atoms are linear in shape, all four atoms lie in a straight line.
Answer:
Fluorine is a <em>non-metal, fills its shell by gaining one electron </em>and<em> becomes a negatively charged ion.</em>
Explanation:
Fluorine have seven electrons in its outermost shell. This means that fluorine is located in Group 17(<em>Halogens</em>) in the Periodic Table. Note that halogens are non-metal elements. So fluorine is a non-metal.
Fluorine fills its shell by gaining one electron because it only needs one electron to achieve stable octet electron arrangement. ( it's easier to gain one electron than to lose all seven electrons in the outermost shell)
As fluorine atom gain one electron to achieve stable octet electron arrangement, its number of electrons becomes greater than its number of protons. So it becomes a negatively charged ion.
