How can we easily remember the atomic mass of different elements?
If you observe the atomic mass of every element is more than two times or nearly 2 times of its atomic number. You have to remember only some elements’ atomic mass as their atomic mass is more than 2 times that of its atomic number. This is one of the easy ways to remember.
How do you remember the atomic weight of the first 30 elements?
Here is the trick for remembering 1 to 30 elements with their atomic number, atomic mass and name. Trick : Double of Atomic number + Magic no. So here is the mnemonic for remembering 1 to 30 elements with their atomic number, atomic mass and name. Have fun learning it !
Do we need to learn atomic mass for JEE?
No such information is pre provided for the exam of IIT JEE mains and advanced. You need to learn the atomic masses and other data that you feel is important for the exam. It is a computer based online exam now and provide just a calculator that you can access from the screen itself.

How can I memorize?
Simple memory tips and tricks
- Try to understand the information first. Information that is organized and makes sense to you is easier to memorize.
- Link it.
- Sleep on it.
- Self-test.
- Use distributive practice.
- Write it out.
- Create meaningful groups.
- Use mnemonics.
What is the formula for finding atomic mass?
The formula mass is calculated by adding up all the atomic masses for every atom in the formula. Note: The atomic mass of an atom is the atom’s mass relative to 1/12th of the mass of a carbon-12 atom on which the standard atomic mass scale is based (e.g. H = 1, C = 12, P = 31 etc).
How do you calculate the atomic mass?
Since the combined masses of protons and neutrons account for almost all the mass of the given atom, the atomic mass of the single atom can be calculated by adding the total number of protons and the total number of neutrons of that particular isotope. The number of protons in a given atom is always equal to its atomic number.
What is atomic mass and how is it determined?
1-The atomic mass number is determined only by the number of nucleons in the nucleus. 2-The atomic mass number is determined only by the number of neutrons in the nucleus. 3-The atomic mass number is determined only by the number of alpha particles emitted.
How do scientists determine the atomic mass of an atom?
Scientists can calculate the number of neutrons by subtracting the atomic number from the atomic mass. The atomic number of an element is the number of protons which can be found in the nucleus of the element’s atoms.
