Answer 1

Hi!

The property shared by all of the elements in group 18 is D) they are all gases.

The elements in group 18 of the periodic table are known as the noble gases and they include elements such as neon, krypton, and xenon.

Answer 2

The correct option is d

Step-by-step explanation:

• Elements in group 18 are referred to as the noble/rare/inert gases because they have a completely filled outermost shell (have achieved there duplet/octet configuration) hence have no valence electron for bonding and are thus stable. There stability makes them electrically neutral (have no charges) and hence have low reactivity. They are colourless, odourless and monoatomic gases.
