Thallium (Tl) has one more proton then mercury (Hg), mercury has 79 protons, Thallium has 80 protons.
A noble gas is an element found in group 18 of the periodic table, characterized by having a full outer electron shell. Therefore, one less proton than a noble gas would place the element in group 17 of the periodic table, known as the halogens. Halogens have one less proton than noble gases and are highly reactive nonmetals.
The element with properties similar to both metals and nonmetals and one less proton than carbon is boron. Boron is a metalloid that displays characteristics of both metals and nonmetals due to its position in the periodic table.
Platinum
Tritium, also know as hydrogen 3, has 2 neutrons and one proton
Thallium (Tl) has one more proton then mercury (Hg), mercury has 79 protons, Thallium has 80 protons.
The element with one more proton than argon is potassium, which has atomic number 19. Argon has an atomic number of 18.
Be is in the s block too. Li has one less proton than Be.
maybe proton
Hafnium (Hf) has one less proton than Zirconium (Zr). Zirconium has 40 protons, while Hafnium has 39 protons.
A proton has slightly less mass than a neutron.
The element with one less proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12.
Niobium (Nb) has one less proton than Zirconium (Zr) in the periodic table. Zirconium has 40 protons while Niobium has 41 protons.
Actually every proton has different size in different nucleus. But in general, Proton, 1x10-15 m or "a diameter of approximately one-millionth of a nanometer". The electron, the diameter is less than 1x10-18 m. Likewise, The diameter of an electron is less than 1/1000 the diameter of a proton.
The element with one less proton than gold is mercury. Gold has 79 protons, while mercury has 80 protons.

Halogens have one less proton than noble gases and are highly reactive nonmetals.
One mole of argon has a lower atomic mass compared to one mole of neon, as argon has a higher atomic number and thus heavier atoms. This means that there are more argon atoms in one mole compared to neon, but since each argon atom is heavier, the overall mass is less.
