Amolecule of antifreeze, ethylene glycol, has the formula c2h4(oh)2. how many atoms are there in one molecule of antifreeze?

the total atoms in one molecule of antifreeze = 2 + 6 + 2 = 10

Explanation:

The number of atoms in the given ethylene glycol molecule can be calculated from its molecular formula.

The molecular formula is :

The subscripts represent the multiplicity of the atoms present

Here the subscript on carbon = 2 so there are two carbon atoms

the subscript on hydrogen = 4 and two on OH, so the total hydrogen atoms = 6

The subscript on oxygen =2 so the total oxygen atoms= 2

Hence the total atoms in one molecule of antifreeze = 2 + 6 + 2 = 10

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 and electronic configuration of phosphorous is .

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.

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.
