Which of the following statements is true about isotopes of the same element? click on all that apply (1 point) isotopes have the same number of protons isotopes have the same number of electrons isotopes have the same number of neutrons isotopes have the same atomic mass isotopes have the same atomic number

Answer : The correct options are,

Isotopes have the same number of protons.

Isotopes have the same number of electrons.

Isotopes have the same atomic number.

Explanation :

Isotope : It is defined as the element that have the same number of protons but have the different number of neutrons of each of the atom.

Atomic number is defined as the number of protons or number of electrons.

Atomic number = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Number of protons

For example :

Carbon - 13:

Mass number = 13

Atomic number = 6

Number of protons = Number of electrons = 6

Number of neutrons = 13 - 6 = 7

Carbon - 12:

Mass number = 12

Atomic number = 6

Number of protons = Number of electrons = 6

Number of neutrons = 12 - 6 = 6

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
