One isotope of a metallic element has the mass number 64 and 34 neutrons in the nucleus. The cation derived from the isotope has 28 electrons.
given,
mass number = 64
number of neutrons = 34
cation derived has 28 electrons
we know that ,
mass number = number of neutrons + number of protons
64 = 34 + number of protons
number of protons = 30
hence number of electrons = 30
atomic number 30
the element is zinc(Zn).
cation derived has 28 electrons
it means 30 electrons - 28 electrons = 2 electrons are out from the element to form a cation of 28 electrons.
which means Zn+2

The longest lived isotope of Tc has 54 neutrons. What is the mass number of this isotope?
II. Isotopes Atoms of a given element all have the same number of protons and electrons, but can have different numbers of neutrons. Versions of the same element with differing numbers of neutrons are call isotopes. The symbol for an isotope is AX Where: A is the mass number (number of protons plus neutrons) Z is the atomic number (number of protons) X is the symbol for the element 2. Show the isotope symbol for the isotope of Fe with...
