- 1 to 50 elements with symbols and atomic number atomic mass . . . - Brainly
The table below consists of 50 elements of the periodic table, sorted by atomic number, atomic weight, and symbols Atomic No It is the number of protons present in the element Atomic mass It is the total number of protons and neutrons present in it Atomic No Atomic Mass Element Name Symbol 1 1 0079 Hydrogen\tH 2 4 0026 Helium He 3 6 941
- 1 to 30 elements with atomic number and round off atomic mass
1-30 represents the atomic number of respective elements Atomic mass: It is defined as the average mass of the elements and it is measured in atomic mass units
- •Which of the following has the highest number of atoms?
For Ag (Silver): Number of moles = Mass Atomic mass = 1 g 108 g mol ≈ 0 00926 mol Number of atoms = Number of moles * Avogadro's number ≈ 0 00926 * 6 022 x 10^23 ≈ 5 57 x 10^21 atoms Comparing the number of atoms calculated for each element, 1g of Li (option c) has the highest number of atoms For the second question:
- Find the radius of nucleus of an atom having atomic mass . . . - Brainly
In this Question , We have Provided with atomic mass number 125 of an atom and we need to find the radius of nucleus Formula to Use : Where , Radius of Nucleus 1 33 * 10^-13 cm ⇒ 1 33 * 10^-15 m ⇒1 33 fermi A = Atomic Mass number of an atom which is equal to 125 Substituting Value in the formula : ⇒ 1 33 * 10^-15 * (125)^ (1 3) ⇒ 1 33
