Question

In which region of the periodic table do the elements NOT normally react chemically with other elements?

A)Metals

B)Metalloids

C)Non-metals

D)Noble Gases

Answer 1

 The region  of the periodic  table that do the elements   not normally react chemically with other elements  is  noble gases(answer  D)

Explanation

• Nobles  gases are element  in group 18   in periodic table.

• They  have  8 electrons in  their  outermost energy  level( their  valence  electrons are  fully filled)

• This  make  noble gases  inert ( an  reactive ) since they  cannot gain or  loss electron .

Answer 2

Answer:

D = Noble Gases

Explanation:

Noble gases are elements found on the extreme left of the period table; the Group 8 elements which means complete outer shell hence complete octet, also called inert elements.

They are odourless, colourless with low chemical reactivity and sometimes exist as monotonic gases with low boiling and melting point. they include: Neon, Argon, Xenon etc.

Elements bond with other elements on the periodic table because of their incomplete outer shell. Bonding ensures that the completed outer shells of both elements by either losing or gaining (ionic bonds) or sharing (covalent bond) id filled as so they form stable compounds. Noble gases are inreactive because of their stability and hence, unlikely to gain or lose electrons.
