An element can be represented symbolically in terms of its atomic number and mass number as:
_{Z}^{A}\textrm{X}
where X = symbol of the element
A = atomic mass
Z = atomic number
In this case we have the representation as:
_{0}^{1}\textrm{n}
where n = symbol for neutron
mass number of neutron = 1
charge/atomic number of neutron = 0
Ans: D) A neutron of zero charge and one unit mass
Size of a sodium ion is smaller than a sodium atom.
Answer: 6.98
The Relative Atomic Mass of Li = (98*7 + 2*6)/98+2
RAM of Li = (686+12)/100
RAM of Li= 6.98
