What does it mean to say the atomic number in an atom?
An atom's atomic number is the number of protons an atom has. This number will never change or the atom becomes a totally different atom.
What does it mean if two atoms are isotopes?
If two atoms are isotopes, it means they have the same number of protons but different numbers of neutrons. Thus, they have the same atomic numbers, but different atomic masses.
What is beryllium mass number?
Beryllium Atomic number: 4 Atomic Mass: 9.012
What does an elemts atomic number mean?
The atomic number is the number of protons and electrons in the element.
When an element have different atomic number and the same mass number what is it called?
Do you mean same atomic number and different mass numbers? If so then these are known as ISOTOPES. All atoms of any given element will have the same atomic number (number of protons in the nucleus) as this is what makes the element what it is. It is the number of neutrons in the nucleus which varies and hence the mass number (the number of protons plus the number of neutrons). For eg Carbon has three ISOTOPES - carbon-12, carbon-13 and carbon-14. They all have atomic number of 6 (6 protons in their nucleii) but have different numbers of neutrons (6, 7 or 8 respectively) and therefore different mass numbers.

How is the element with atomic number 82 in the periodic table different from the element in the atomic number 81?
The atomic number the the number of protons and therefore the total positive charge in the nucleus. So the the element with the atomic number 82 has more protons and a greater nuclear charge then the atomic number of 81. More protons can mean many different things such as a smaller radius, greater first ionisation energy or greater electronegativity.
What is rubidiums atomic number and what those it mean?
atomic number is 37
What is beryllium mass number?
Beryllium Atomic number: 4 Atomic Mass: 9.012
What does an elemts atomic number mean?
The atomic number is the number of protons and electrons in the element.
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
Idotopes of the same element have different?
if you mean isotopes then isotopes of the same element have a different number of neutrons in the nucleus so have a different atomic weight.
How does the atomic number compare with the atomic weight?
The different isotopes have different Atomic Mass numbers, because the isotope has different numbers of neutrons. The protons and electrons are the same, so the change in mass number is the same as the change in the number of neutrons.
What subatomic particle gives you the atomic number?
Protons.The atomic number of an atom is the number of protons in the atom. The identity of an atom is based on its atomic number, so a change in the number of protons mean an atom has turned into a different element. However, an addition or subtraction of neutrons creates different isotopes of an element, and a change in the number of electrons creates an ion of the element.
What does the atomic number for californium mean?
The meaning of the atomic number is: number of protons and electrons (for californium is 98).
Gold has an atomic number of 79 What does the 79 mean?
The atomic number is the number of protons in the nucleus of the atom.
