Calculation of Mass Number for Isotopic Elements. When a component has an isotope, the nucleon numbers are often calculated by the various proportions it exists in. For example take 98% Carbon-12u and 2% Carbon-13u. This doesn't mean that any Carbon atoms exist with the nucleon number of 12.02u. Example of Isobar are : Argon, potassium, and calcium having atoms of the same mass number 40. 18Ar40, 19K40, 20Ca40 where 18, 19 and 20 shown as subscripts are the atomic numbers of the three elements respectively are isobars. Since the atomic numbers are … This model proposed that atom is considered asa uniform positively charged sphere and electrons are embedded in it.An important feature of Thomson model of an atom was that mass of atom isconsidered to be evenly spread over the atom 18AR40 and 20Ca40.

Is no. of element? Some reply yes.

Isoton adalah unsur-unsur yang berbeda tetapi mempunyai jumlah netron yang sama. Contoh : 6C14 dan 8O16 6C14 p = 6 n = 14 – 6 = 8 8O16 p = 8 n = 16 – 8 = 8 * By farid Qim Iya 2000 Isoelektron adalah unsur atau ion dengan jumlah elektron sama. A marked influence of the exchange processes on the radiation properties of the nucleus exists even in the limit considered. Numerical computations are carried out for 8O16 and 20Ca40.

Examples are, 20Ca40and 18Ar40 Uses of isotopes: The isotope of Iodine atom is used to treat goitre and iodine deficient disease. In the treatment of cancer, an isotope of cobalt is used. Fuel for nuclear reactors is derived from the isotopes of the Uranium atom.

IV. This means it will not be considered as a business expense and will be added back to the income. Further, it will result in a higher payment of taxes. However, Rule 6DD prescribes certain cases and circumstances where the above mentioned expenditures will be allowed as deduction even if payment is made in Cash. - Two or more forms of an element having the same atomic number, but different mass number are called Isotopes (17Cl35, 17Cl37). - Atoms of different elements having the same mass number, but different atomic numbers are called Isobars (18Ar40, 20Ca40). Isotope Definition and Examples in Chemistry.

For example take 98% Carbon-12u and 2% Carbon-13u. This doesn't mean that any Carbon atoms exist with the nucleon number of 12.02u. Example of Isobar are : Argon, potassium, and calcium having atoms of the same mass number 40.

So isobars are the atoms if different elements having same mass number but different atomic numbers .

Their atomic numbers are different. But their atomic mass is same i.e. For eg - 18Ar40 and 20Ca40. Argon and calcium are two different elements but their atomic mass is same and atomic nos. are different. As argon has atomic no.
