Element with atomic number 4 and 18( from the alkaline earth and noble gas family) form 1:1 compound which is polar. What is the compound colour and formula?
Answers
Explanation:
re the 18 groups of the periodic table?
The noble gases are the 18th group in the periodic table. They consist of Helium (He), Neon (Ne), Argon (Ar), Krypton (Kr), Xenon (Xe), and Radon (Rn). They were previously called Inert gases due to their inert properties. This short article about chemistry can be made longer

Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og). The noble gases are colourless, odourless, tasteless, nonflammable gases. They traditionally have been labeled Group 0 in the periodic table because for decades after their discovery it was believed that they could not bond to other atoms; that is, that their atoms could not combine with those of other elements to form chemical compounds. Their electronic structures and the finding that some of them do indeed form compounds has led to the more appropriate designation, Group 18.
