Q. Why is no oxidation number assigned to Group 18 the noble gases?
The elements of group 18 all have closed-shell valence electron configurations, either ns2np6 or 1s2 for He. 1 indicate that the noble gases are unlikely to form compounds in negative oxidation states. A potent oxidant is needed to oxidize noble gases and form compounds in positive oxidation states.
Q. What is the state of all elements in group 18?
noble gases

Q. What does Zn 2 mean?
Zinc ion
| PubChem CID | 32051 |
|---|---|
| Description | Zinc(2+) is a divalent metal cation, a zinc cation and a monoatomic dication. It has a role as a human metabolite and a cofactor. ChEBI Zinc cation is a Copper Absorption Inhibitor. The physiologic effect of zinc cation is by means of Decreased Copper Ion Absorption. FDA Pharm Classes |
Q. Is Zn 2 stable?
Zinc is the 24th most abundant element in Earth’s crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral….

Q. What is the biggest atom in the universe?
What Marinov of the Hebrew University of Jerusalem and his colleagues claim to have discovered is a monstrous atom with by far the heaviest nucleus ever seen, packing a whopping 122 protons and 170 neutrons. Crucially, the team had not synthesised it in the lab, but found it in nature, in a sample of purified thorium.
Q. What is the smallest thing in universe?
Protons and neutrons can be further broken down: they’re both made up of things called “quarks.” As far as we can tell, quarks can’t be broken down into smaller components, making them the smallest things we know of.
Q. What is the smallest observable particle?
electron neutrino
Q. Which is the smallest subatomic particle?
quarks
