In periodic table of elements it is the sum of the number of protons and neutrons of an atom.?
The sum of protons and neutrons is the atomic mass.
Are protons neutrons and electrons elements?
No, protons, neutrons, and electrons are not elements. Protons and neutrons are subatomic particles found in the nucleus of atoms, while electrons orbit the nucleus. Elements are substances made up of one type of atom, characterized by the number of protons in their nucleus.
What two factors determine the atomic mass of an elements?
neutrons and protons
An atoms mass number equals the combination of what two things?
An atom's mass number is the total number of protons and neutrons in its nucleus.
How are elements determind?
Elelments are determined by the amount of protons they have. While different elements can have the same number of neutrons and protons, no two different elements can have the same amount of protons.
How did scientists discovering protons and neutrons help them to place elements in their correct order and group?
By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.
How is the periodic table used to arrange the elements?
The periodic table used to be arranged by increasing atomic mass. Now, it is arranged by increasing atomic number (number of protons in an atom of element).
Lighter elements have more or less number of protons than neutrons?
Lighter elements tend to have neutrons equal to protonms or only a slight excess. Heavier elements have an excess of neutrons over protons
What are the group of elements?
Protons, neutrons and electrons
what is the atom that elements are made of?
An atom is made from neutrons, protons and electrons; neutrons and protons contain quarks and gluons.

Are protons and neutrons elements?
LOL! Nah they aren't.
Name 3 elements?
Protons,Neutrons and Nucleus
