Question

Complete each statement with the word that makes it true.

The noble gases are the least blank
of any elements on the periodic table.

The blank form acidic compounds with hydrogen.

The halogens are the most reactive among all the
blank.

Answer 1

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

1) The Noble gas are the least reactive of any elements in the periodic table.

Reason :- Because their octet,or duplet is completed.

2) Chlorine form acidic compound with hydrogen.

Reason :- when chlorine react with hydrogen to form HCl gas but when they come in contact with moisture it gives hydrogen ion and show the property of acids.

3) The halogens are the most reactive among all the elements.

Reason :- The electronic configuration of noble gas has seven electrons in their last shell so they need one electron to become stable that's why they are most reactive among all elements.

Answer 2

Answer:

1)Reactive

2)Chlorine

3)Elements
