metals tend to form cations
nonmetals tend to form anions
this is because metals lose electrons,
and nonmetals gain electrons
The atomic mass of X₁ is 14 and the name of the element is Nitrogen.
The atomic mass of X₂ is 16 and the name of the element is Oxygen.
The atomic mass of X₃ is 32 and the name of the element is Sulfur.
The given parameters include:
weight C weight X
Compound 1 4.2 4.9
Compound 2 3.5 4.67
Compound 3 1.3 3.47
The atomic mass of the first compound (X₁) is calculated as follow;
let the total mass of X₁ and C = T
X₁ + C = T
X₁ + C = T
X₁ + 12 = 26
X₁ = 26 - 12
X₁ = 14
The atomic mass of X₁ is 14 and the name of the element is Nitrogen.
The atomic mass of the second compound (X₂) is calculated as follow;
let the total mass = P
The atomic mass of X₂ is 16 and the name of the element is Oxygen.
The atomic mass of the third compound (X₃) is calculated as follow;
Let the total mass = y
The atomic mass of X₃ is 32 and the name of the element is Sulfur.
