What is atomic number and atomic weight?
Each atom, therefore, can be assigned both an atomic number (the number of protons equals the number of electrons) and an atomic weight (approximately equaling the number of protons plus the number of neutrons).
What is the 22nd element?
Titanium – Element information, properties and uses | Periodic Table.
What element has the highest atomic weight?
Ununoctium is the heaviest element, but it is man-made. The heaviest naturally-occurring element is uranium (atomic number 92, atomic weight 238.0289).
What are the elements of an atom?
The three basic components of an atom are: protons, neutrons, and ions. protons, neutrons, and electrons. protons, neutrinos, and ions. protium, deuterium, and tritium .
Atomic number and atomic weight are two chemical terms that are used to explain the number of subatomic particles present in an atom and its mass. The main difference between atomic number and atomic weight is that atomic number gives the number of protons present in the nucleus whereas atomic weight gives the mass of an atom.
What are monatomic elements?
Monoatomic elements are those elements which have a single atom existing individually in nature. For examples when you talk about hydrogen, oxygen you will write their chemical structure as H2 and O2.
