Complete each statement with the word that makes it true. the noble gases are the of any elements on the periodic table. the form acidic compounds with hydrogen. the halogens are the most reactive among all .


Answer 1

Noble gases are the smallest reaction of any elements on the periodic table.


All the elements in Group Zero are noble gases. The list includes helium, neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). They are also called inert gases because they do not react with other elements of the periodic table. The reason behind their inertia is that their outermost shell is complete and does not have the tendency to lose or gain electrons.

Answer 2:

The Halogens form acidic compounds with hydrogen


The non-metals in group 7 of the periodic table are called the halogens. When they react with hydrogen their respective acids are formed For example, hydrogen chloride (HCl) is produced when hydrogen combines with Chlorine and in the same way hydrogen bromide is produced when bromine reacts with hydrogen.

Answer 3:

They are the most reactive halogens of all non-metals


The non-metallic elements in Group 7 are composed of halogens and are composed of five chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They become less reactive as we go down the group. This is the opposite of the trend of the alkali metals in Group 1 of the periodic table which are reactive among metals.
