FAQs on Atomic Mass & Atomic Number Video Lecture - Physical Chemistry for NEET

1. What is the atomic mass of an element?
Ans. The atomic mass of an element is the weighted average mass of all the isotopes of that element found in nature. It is expressed in atomic mass units (u) or grams per mole (g/mol).
2. How is the atomic mass calculated?
Ans. The atomic mass of an element is calculated by taking into account the mass and relative abundance of each isotope of that element. The mass of each isotope is multiplied by its abundance, and the results are then summed to obtain the atomic mass.
3. What is the atomic number of an element?
Ans. The atomic number of an element is the number of protons present in the nucleus of an atom of that element. It uniquely identifies the element and determines its position in the periodic table.
4. How is the atomic number determined?
Ans. The atomic number of an element is determined by the number of protons in the nucleus of an atom of that element. It can be found by looking up the element on the periodic table, where the atomic number is listed above the element's symbol.
5. What is the relationship between atomic mass and atomic number?
Ans. The atomic mass and atomic number of an element are related but represent different properties of an atom. The atomic number represents the number of protons in the nucleus, while the atomic mass is the weighted average of the masses of all the isotopes of that element. The atomic mass may vary slightly from the whole number atomic number due to the presence of different isotopes.
