Give the nuclide symbol for an atom that has<br> mass number 64 and 35 neutrons.
azamat
The mass number represents the summation of the number of protons and the number of neutrons in the nucleus of an atom.
We are given that the mass number is 64 and that the number of neutrons is 35. Therefore:
number of protons = 64 - 35 = 29 protons

In ground state, number of protons in an atom is equal to the number of electrons. Therefore,
number of electrons = 29 electron

Using the periodic table, we will find that the element that has 29 electrons in ground state is copper.
The nuclide symbol of copper is shown in the attached image.

Which of these is a pair of coordination isomers (aka ionization isomers)?
vagabundo [1.1K]

Answer:  [Ni(NH_3)_3Br]Cl and [Ni(NH_3)_3Cl]Br are ionization isomers.

[Pt(Cl)_2(SCN)_4]^{4-} and [Pt(Cl)_2(NCS)_4]^{4-} are linkage isomers.

Explanation:

Ionization isomerism occur when a ligand that is bound to the metal center exchanges places with an anion or neutral molecule that was originally outside the coordination complex

Thus [Ni(NH_3)_3Br]Cl and [Ni(NH_3)_3Cl]Br are ionization isomers.

Linkage isomerism is the existence of coordination compounds that have the same composition differing with the connectivity of the metal to a ligand.

Thus [Pt(Cl)_2(SCN)_4]^{4-} and [Pt(Cl)_2(NCS)_4]^{4-} are linkage isomers.
