Answer asap: what term would you use to describe neon, helium, lithium, sodium, and potassium?

-

Neon, Helium = Noble gas

Lithium, Sodium, and Potassium = Alkali metals

Explanation:-

Neon has the electronic configuration 2,8

It has eight electrons in it's valence shell. As such it is stable as per the octet rule. Hence Neon is a noble gas.

Helium has the electronic configuration 2.

As per the duplet rule. it is stable. Hence Helium is a noble gas.

Lithium has the electronic configuration 2,1

Sodium has the electronic configuration 2,8,1

Potassium has the electronic configuration 2,8,8,1

Lithium, Sodium and Potassium each have 1 valence electron in it's outermost shell. The group of metals with 1 valence electron is called Alkali metals.

Hence Lithium, Sodium and Potassium are called alkali metals.

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
