The number of protons in the atomic nucleus of lead is 82 whereas in gold it is 79
If you add a proton, neutron, and electron to a gold atom, you would obtain a new element called Mercury (symbol: Hg). This new element would have a different number of protons, neutrons, and electrons compared to gold.
The will depend on the type of atom. The number is different for an atom of hydrogen, lead, gold, fluorine, etc.
Lead is an element. Every atom in the metal is a lead atom. That makes it different from metal alloys, like bronze, the atoms within which are copper and usually tin.
An atom of lead has more mass than an atom of gold. This is because lead has a greater atomic mass than gold, due to the larger number of protons, neutrons, and electrons in a lead atom compared to a gold atom.
Lead and gold are elements, made up of completely lead and gold atoms, respectively. Elemental atoms cannot be created or changed. They can only combine to form molecules. An element can never become another element.
Lead is a metal element. There are 82 electrons in a single atom.
An atom of lead has more mass than an atom of gold. This is because lead has a higher atomic number than gold, meaning it has more protons and neutrons in its nucleus, resulting in a greater atomic mass.
Lead is a chemical metal element. There are 82 electrons in a single atom.
An element is a substance that has one kind of atom.
82 protons
An element atom with 80 protons is lead (Pb) on the periodic table.
