B. Write the chemical equation using formulas and symbols.

D. Count the atoms in each substance in the reactants and products,

Explanation:

When balancing chemical equation, it implies that the law of conservation of matter be strictly adhered to.

By so doing, the number of atoms on both sides of the reaction must be the same. Number of atoms in the products and reactants must have the same value.

It is always a good approach to first write the chemical equation of the reaction. This will give an overview of the reacting species and the products being formed. Then, go on to count the number atoms in the reactants and product sides of the expression. Then balance it using any of the method of balancing chemical equations.

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
