List the symbols for all the elements with electron configurations that end as follows. Each n represents an energy level.

a. ns1

b. ns2np4

Answer: a) H, Li, Na, K, Rb, Cs, and Fr

b) O, S, Se, Te, Po

Explanation:

a. Determining the elements correlating to the electron configuration of "ns1" , you should understand that this suggests that the elements are in Group 1A.

This is because that there is one electron in an s-orbital. The orbital is located in the first column of the periodic table.

Thus, the elements that have this electron configuration are H, Li, Na, K, Rb, Cs, and Fr.

b. Determining the elements correlating to the electron configuration of ns^2np^4 characterizes group 6A of the periodic table.

This is because that there is have six valence electrons in their highest-energy orbitals (ns2np4). The orbital is located in the first column of the periodic table.

Thus, the elements that have this electron configuration are the nonmetals oxygen (O), sulfur (S), and selenium (Se), the metalloid tellurium (Te), and the metal polonium (Po).

Which example is a homogenous mixture of two or more pure substances? alcohol
il63 [147K]

Answer:

Alcohol and water.

Explanation:

Alcohol and water is a homogenous mixture. because these two liquids are soluble, miscible in all composition. A homogenous mixture is a solution that has equal  composition of its components.

Irregular mixing of two liquid components have different refractive indexes. At a high temperature, it can become inhomogenous spontaneously.

A solution is a type of homogenous mixture which composed of two or more substances. In a mixture a solute is a substance, dissolves in other substance that is solvents like alcohol and water, alcohol is solute and water is a solvent.
