This is called the Mass Number of the isotope of the atom.
Isotopes are different forms of the same atom. They have the same number of protons but different number of neutrons.
Carbon-12 has mass number 12 as it has 6 protons and 6 neutrons.
Carbon-14 has mass number 14 as its has 6 protons and 8 neutrons.

Answer:
Balanced Chemical equation:
4Na + O₂ → 2Na₂O
Explanation:
Chemical equation:
Na + O₂ → Na₂O
Balanced Chemical equation:
4Na + O₂ → 2Na₂O
Four mole of sodium combine with one mole of oxygen and form two mole of sodium oxide.
Coefficient with reactant and products:
Na 4
O₂ 1
Na₂O 2
Oxygen is present in group sixteen and have six valance electrons. while sodium is alkali metal and present in group one and have one valance electron.
Oxygen needs two electron to complete the octet while sodium need to lose the one electron to get the complete octet.
When oxygen is combine with sodium it gain its two valance electrons from two sodium atom and form anion while sodium loses its valance electron to wards oxygen and form cation. The bond form between them is ionic because one is metal and other is non metal and electrons are completely transfer from two sodium atom to one oxygen atom.
Answer:
Explanation:
Hydrocarbon:
a = An organic compound made up of only carbon and hydrogen.
Such as alkane, alkene, alkyne.
Cyclic hydrocarbon:
c = Carbon chain that form rings.
Such as benzene, cyclo heptane etc
Isomers:
d = Compounds with same molecular formula and different structural formula.
Alkanes:
e = refers to saturated hydrocarbons, no matter the shape
such as methane, ethane, propane etc.
Alkene:
f = Any hydrocarbon that have at lest one carbon carbon double bond.
such as ethene, propene, butene
Saturated hydrocarbons:
b = Carbon atoms are saturated with so many hydrogen atoms that no more bonds may be formed
such alkanes.
