An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
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.
How many neutrons does cesuim 133 have in isotopes?
54 protons 79 neutrons 54 electrons
What two factors determine the atomic mass of an elements?
neutrons and protons
What are the sub-atomic particles of uranium?
Protons, neutrons and electrons - as in all the other chemical elements.
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
An atoms mass number equals the combination of what two things?
The mass number of an element is equal to the sum of the elements neutrons and protons.
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.
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.
Is gold a proton?
Yes it does. All elements have electrons, protons, and neutrons.
How many neutrons does cesuim 133 have in isotopes?
54 protons 79 neutrons 54 electrons
Are protons and neutrons elements?
LOL! Nah they aren't.
Name 3 elements?
Protons,Neutrons and Nucleus
What are the sub-atomic particles of uranium?
Protons, neutrons and electrons - as in all the other chemical elements.
