To determine:
The number of electrons, protons, and neutron in
Introduction:
The mass number of the atom is the sum of neutrons and protons in the atom. The atomic number of atom is equal to the number of protons. The isotopes are the elements having same atomic number but different mass number.

- Describe how Dalton obtained relative atomic weights.arrow_forwardDefine the term atomic weight. Why might the values of atomic weights on a planet elsewhere in the universe be different from those on earth?arrow_forwardHow many platinum atoms are in a pure platinum ring weighing 4.32 g?arrow_forward
- How many Ag atoms are present in a piece of pure silver jewelry weighing 21.3 g?arrow_forwardRadon is a radioactive gas that can cause lung cancer. It has been detected in the basement of some homes. In an atom of Rn-220, (a) how many protons are there? (b) how many neutrons are there?arrow_forwardFor the following isotopes that have missing information, fill in the missing information to complete the notation (a) X1434 (b) PX36 (c) MX57n (d) X56121arrow_forward
- The element rhenium (Re) bas two naturally occurring isotopes, 185Re and 187Re, with an average atomic mass of 186.207 u. Rhenium is 62.60% 187Re, and the atomic mass of 187Re is 186.956 u. Calculate the mass of 185Re.arrow_forward40K is used to measure the age of Earth. Determine the number of protons and neutrons in 40K.arrow_forward2.86 For some uses, the relative abundance of isotopes must be manipulated. For example, a medical technique called boron neutron capture therapy needs a higher fraction of 10B than occurs naturally to achieve its best efficiency. What would happen to the atomic weight of a sample of boron that had been enriched in 10B? Explain your answer in terms of the concept of a weighted average.arrow_forward
