When the number of protons and electrons are equal, that means the element is neutral. So, to know the element, find the element with an atomic number of 10. That would be Neon. Next, solve the mass number.
Mass number = protons +neutrons = 10+11 = 21
Thus, the expression should be written as shown in the attached picture.
Mass number = protons +neutrons = 10+11 = 21
Thus, the expression should be written as shown in the attached picture.
Given that,
The equation is :
To find,
The missing coefficients.
Solution,
Let the value of ? is x.
It is the equation of photosynthesis.
In LHS,
Carbon atoms = 6
Hydrogen atom = 12
Oxygen atom = 18
In RHS,
Carbon atoms = 6
Hydrogen atom = 12
Oxygen atom = 6
If we make the equation as
No the number of atoms in RHS = 6+ 12 = 18
It means if we take the value of ? as 6 the equation will be balanced.
Hence, the correct option is (B) "6".
