Give the relation between atomic number and atomic mass of light elements?
Example :
Carbon (C) is a light element
Atomic number of Carbon = 6
Atomic mass of Carbon = 2 x 6 = 12 amu (amu =Atomic mass unit)
(a) What is meant by (i) atomic number, and (ii) mass number, of an element? Explain with the help of an example.
(b) What is the relation between the atomic number and mass number of an element?
(c) If an element M has mass number 24 and atomic number 12, how many neutrons does its atom contain?
What is Valency and atomic mass of all elements in whole number?
Give only 1 valency and atomic mass for 1 elements.
There are two elements A 26 mass number and 13 atomic number and B 26 mass number and 14 atomic number . find the number of sub atomic particles in each of these elements.what is the relationship between the two?
