Platinum(Pt) has 78 protons. Gold(Au) has 79 protons
When a gold nucleus loses a proton, it is transformed into a mercury nucleus. Mercury has an atomic number of 80, one less than gold's atomic number of 79.
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.
Silver is less dense than gold. Gold has a higher density compared to silver, which means that a unit volume of gold will have more mass than the same volume of silver.
The element with one more proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12 protons.

When a gold nucleus loses a proton, it is transformed into a mercury nucleus. Mercury has an atomic number of 80, one less than gold's atomic number of 79.
The element with one less proton than sodium is magnesium. Sodium has 11 protons, while magnesium has 12.
Thallium (Tl) has one more proton then mercury (Hg), mercury has 79 protons, Thallium has 80 protons.
When a mercury-202 nucleus is bombarded with a neutron and a proton is ejected, the resulting nucleus will have one less proton than the original mercury nucleus. Mercury (Hg) has an atomic number of 80, so after losing a proton, the new element formed will be gold (Au), which has an atomic number of 79. Thus, the reaction transforms mercury-202 into gold-201.
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.
Niobium (Nb) has one less proton than Zirconium (Zr) in the periodic table. Zirconium has 40 protons while Niobium has 41 protons.
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.
Be is in the s block too. Li has one less proton than Be.
Silver is less dense than gold. Gold has a higher density compared to silver, which means that a unit volume of gold will have more mass than the same volume of silver.
Platinum
an electron has way less mass than a proton.
