Seventeen elements are generally classified as nonmetals: most are gases (hydrogen, helium, nitrogen, oxygen, fluorine, neon, chlorine, argon, krypton, xenon and radon);
one is a liquid (bromine); and a few are solids (carbon, phosphorus, sulfur, selenium, and iodine). Metalloids such as boron, silicon, and germanium are sometimes counted as nonmetals.
ANSWER:
Liquid:
Bromine - Br - 35
Solid:
Carbon - C - 6
Phosphorus - P - 15
Sulfur - S - 16
Selenium - Se - 34
Iodine - I - 53
Answer is: E- None of these.
NiCl₂ is nickel(II) chloride. Nickel chloride is salt.
KMnO₄ is p<span>otassium permanganate. P</span>otassium permanganate is salt.<span>
ZnSO</span>₃ is zinc(II) sulphite. Zinc sulphite is salt.<span>
SO</span>₂ is sulfur(IV) oxide. Sulpfur oxide is oxide. Oxidation number of sulfur is +4 and oxygen has oxidation number -2.
An ion usually has all of its electrons paired up whereas free radicals have one or more unpaired
yes and no gold is super dense but malleable lead is dense but brittle so no.
Being as hydrogen is the lightest element it works most efficiently as lift in our atmosphere which is mostly made of heavier nitrogen.
