Answer from: corcoranrobert1959

It is a heterogeneous mixture

Explanation:

A mixture is a substance that is formed by several components (two or more), which do not lose their properties and characteristics due to the mixing because there is no chemical reaction between them.

Homogeneous mixtures: Those mixtures whose components cannot be distinguished with the naked eye. The homogeneous mixtures of liquids are known as solutions and consist of a solute and a solvent, the first being the one in smaller proportion and also usually the liquid. For example, water mixed with mineral salts or sugar, water would be the solvent and sugar the solute.

Heterogeneous Mixtures: A heterogeneous mixture is one that has a non-uniform composition in which its components can be distinguished with the naked eye and is formed by two or more substances, physically different, unevenly distributed. The parts of a heterogeneous mixture can be separated mechanically. For example, water and sand, water and sludge, water and oil

Answer from: Quest

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is $1s^{2}2s^{2}2p^{6}3s^{1}$ and electronic configuration of phosphorous is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{3}$ .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

$3na + p \rightarrow na_{3}p$

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

Electrons are transferred from atoms of to atoms of this transfer makes the sodium atoms and the
