If two atoms are isotopes of the same element the atoms must have
kodGreya [7K]

Answer:

Same number of protons but different number of neutrons

Explanation:

Isotopy is a phenomena in which atoms of the same element differs by the number of neutrons in their nucleus. While it is important to note that they have the same number of protons and hence the same atomic number, they have different mass numbers.

They have the same atomic numbers because an element can only have one atomic number. Hence, all atoms of that element are composed of the same number of protons but different neutron numbers.

The combined gas law states that
seropon [69]

Answer:

Option B. PV = nRT.

Explanation:

From the above,

C = PV / T. (1)

But, C is directly proportional to n, where R is the gas constant i.e

C & n

C = nR

Substituting the value of C into equation (1), we have:

C = PV / T

nR = PV / T

Cross multiply to express in linear form

nRT = PV

Therefore,

PV = nRT
