Acertain radionuclide is used to diagnose lymphoma. an atom of this radionuclide contains 31 protons and 36 neutrons. which statement is correct about the radionuclide?
a. the atomic number is 31, the mass number is 67, and its symbol is 67/31 ga.
b. the atomic number is 31, the mass number is 67, and its symbol is 31/64 ga.
c. the atomic number is 67, the mass number is 31, and its symbol is 67/31 ga .
d. the atomic number is 67, the mass number is 31, and its symbol is 31/64 ga .

 A. The atomic number is 31, the mass number is 67, and its symbol is

Explanation:

Atomic number is defined as the number of protons or number of electrons that are present in an electrically neutral atom.

Atomic number = Number of protons = 31

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons  = 31 + 36 = 67

The isotopic representation of a radionuclide is:

where,

Z = Atomic number of the atom

A = Mass number of the atom

X = Symbol of the atom

Thus the atom is written as

they it depends on if one believes about radioactivity, they make a geiger counter beep but maybe it was going to beep anyway electronics do wierd things all the time or it was programmed to beep near certain metals.

colorless gas, exhibiting a blue glow when placed in an electric field

b) solid

its a type of rock
