Define the atomic mass unit.
What is meant by atomic mass number?
What are polyatomic ions? Give two examples.
Define the term:
Mass number
Explain the following:
An element has atoms with different mass numbers.
Ordinary chlorine gas has two isotopes \[\ce{^35_17Cl}\] and \[\ce{^37_17Cl}\] in the ratio of 3 : 1. Calculate the relative atomic mass of chlorine.
Write down the mass number of the atom having 20 neutrons and 15 protons.
What would be the reason for an element to have atoms with different mass numbers?
Select the correct answer from the answer in the bracket to complete the sentence.
An element has electronic configuration 2, 8, 1 and 12 neutrons. Its mass no. is ________.
Give a reason for the following:
The mass number of an atom is slightly less than the actual atomic mass.
Draw the structure of oxygen and sulphur atoms.
Which of the following represents 1 amu?
The gram atomic mass of an element has no unit.
Answer the following question using the data given below:
- Assertion: The Relative Atomic mass of aluminium is 27
- Reason: An atom of aluminium is 27 times heavier than 1/12th of the mass of the C – 12 atom.
Calculate the % of oxygen in Al2(SO4)3. (Atomic mass: Al-27, O-16, S -32)
Chlorine exists in two isotopic forms, \[\ce{Cl-37}\] and \[\ce{Cl-35}\] but its atomic mass is 35.5. This indicates the ratio of \[\ce{Cl-37}\] and \[\ce{Cl-35}\] is approximately
If the atomic mass unit ‘u’ were defined to be `1/5 "th"` of the mass of an atom of C-12, what would be the atomic weight of nitrogen in amu or ‘u’ in this state? Atomic weight of N on the conventional scale is 14.
