No- it has 1 more neutron
magnesium has 1 more proton than sodium. Magnesium belongs to group-2
I believe your question is incomplete. What is an inert gas and has one more proton... one more proton than what, exactly? Than hydrogen? If so, the answer would be helium.
Platinum
This statement is incorrect. A proton has a mass that is approximately 1836 times greater than that of an electron.
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
an electron is much lighter than a proton or neutron.

Proton has a greater mass than the electron.
No. A proton is many times more massive than an electron.
No. A proton is many times more massive than an electron.
This statement is incorrect. A proton has a mass that is approximately 1836 times greater than that of an electron.
The atomic number is equivalent to its number of protons. One proton in atom is its atomic number is 1. Hydrogen is the only atom with one proton.
The element with one more proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12 protons.
In kilograms, an electron's mass is ~9 x 10^(-31). A proton's mass is ~1.7 x 10^(-27). The mass of the proton is more than 1000 times of an electron.
A proton has a mass slightly less than that of a neutron. A neutron is slightly more massive due to the extra mass of an additional electron.
