19) The reaction between solid white phosphorous and oxygen produces solid tetraphosphorous decaoxide (P4010). The balanced
equation is given below:
P4 +502 P4010
What is the limiting reactant if you are using 25.0 grams of phosphorus and 50.0 grams of oxygen?
A)
02
B)
P4
0
P4010
D)
P402

did you find the answer?

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
