isotopes mass

Isotopes are atoms of the same element having different atomic mass but same atomic number. For e.g., there are three isotopes of hydrogen with atomic mass 1, 2, and 3. According to Mendeleev's periodic table these should be placed at three separate places. ..

These are the elements having same atomic number but different mass number. They have the same atomic number because the number of protons inside their nuclei remains the same. The difference in their mass number is due to the difference in their number of neutrons. Since they ..

Isotopes are the different forms of the same element, which have the same atomic number but different mass numbers. The isotopes of hydrogen are protium, deuterium and tritium with mass number 1, 2 and 3 respectively. The relative abundance of three iso..

The atomic mass of an element is a relative quantity and is the mass of one atom of the element relative to the mass of one carbon-12 atom. Thus,Relative atomic mass (RAM) of an element is the number of times one atom of an element is heavier than 1/12 the ..

The mass of 1/12 th 12 C isotope of carbon is now the standard used for defining one atomic mass unit (a.m.u). It is equal to 1.66 x 10 -24..

The scale in which the relative atomic masses of different atoms are expressed is called atomic mass unit scale. Atomic masses are not expressed as whole numbers because natural elements are mixtures of two or more isotopes. The atomic weight of chlorine i..

It is very difficult to accurately weigh the number of atoms as they are extremely light and small and they cannot be seen. Indirect methods have been utilized to determine the absolute mass of an atom...

. Relative atomic mass of an element is the number that represents, the number of times one atom of the element is heavier than 1/12 t h of the mass of one atom of carbon Thus relative atomic mass of an element is the mass of its atom expressed in atomic ..
