Concept explainers
Interpretation: The special property of the Noble gases which makes them unreactive needs to be explained and also the reason of increase of boiling points and melting points of the Noble gas from He to Xe needs to be explained.
Concept Introduction:
In the Long form of periodic table, the non-metals are mainly placed at the right side of the periodic table that is called as p-block elements.
Metals make the 75 % part of the periodic table. Metals are electropositive elements and mainly form ionic compound, whereas non-metals are electronegative elements and can form either covalent or ionic compounds.
Noble gases are the elements which are placed in the group-0 of the periodic table at the right most side of the main body of the periodic table.

- Hydrogen is by far the most abundant element cosmically. Ininterstellar space, it exists mainly as H₂. In contrast, on Earth, itexists very rarely as H₂and is ninth in abundance in the crust.Why is hydrogen so abundant in the universe?

- Which group(s) of the periodic table is (are) described byeach of the following general statements?(a) The elements form compounds of VSEPR class AX₃E.(b) The free elements are strong oxidizing agents and formmonatomic ions and oxoanions.(c) The atoms form compounds by combining with two otheratoms that donate one electron each.(d) The free elements are strong reducing agents, show only onenonzero oxidation state, and form mainly ionic compounds.(e) The elements can form stable compounds with only threebonds, but as a central atom, they can accept a pair of electronsfrom a fourth atom without expanding their valence shell.(f) Only larger members of the group are chemically activearrow_forwardSelect one of the alkali metals and write a balanced chemical equation for it's reaction with chlorine.
