What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
What do the numbers on mendeleev's periodic table represent?
The Atomic number which is the number of protons in an atom's nucleus.
How do you determine the atomic number?
They use a mass spectrometer. The atomic number equals the number of protons in the nucleus of the atom. It required a bit of work to figure out originally (the mole number and Avogardo played a big part). The trouble with the mass spectrometer is that it works with compounds as well as elements ... it was a late development.
How many nucleons are there in magnesium?
24, it's the number of protons and neutrons, i.e. the number of sub-atomic particles in the nucleus.
How many protons does an atomic number of 6 and a mass number of 14 have?
The mass number of an isotope of an element is defined as the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope. The atomic number is defined as the number of protons only in the nucleus. Therefore, an atom with an atomic number of 6 has 6 protons in its nucleus.
What is the subatomic particles on which the atomic number is based?
Number of protons in the nucleus is the atomic number.
What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
The atomic number is the same as the same as the number of these particles what are they?
The atomic number is the number of protons in the nucleus. The protons are positive particles, and so the number of them is matched by the number of electrons orbiting the nucleus. The organisation of the electrons determines how an element behaves when it reacts.
How do you know which element have the greatest number of protons in their nucleus?
The elements with the highest atomic numbers have the greatest numbers of protons in their nucleus, because that is the definition of atomic number.
The atomic number for an element is the total number of subatomic particles?
False; the atomic number is the total number if protons in the nucleus only.
What is the atomic number and what does the atomic number indicate?
Atomic number is the number of protons in the nucleus of an atom. The periodic table is arranged in an order of increasing atomic numbers.
What is ment by atomic number?
Atomic Number is the amount of Protons (positively charged subatomic particles) contained in the nucleus of an atom.
Protrons are particles that are?
Protons are the positively charged particles that are present in the nucleus of the atom and their number determines the atomic number of the atom.
What do the numbers on the periodic table mean?
On the periodic table, there are two numbers for every element: the atomic number and the atomic weight. The numbers at the top of the square represents the number of protons present in the atom's nucleus of that element. This is called the atomic number. For example, the atomic number for the element Krypton is 36. That means that there are 36 protons in the nucleus. If there were not 36 protons in the nucleus of that atom, that would create the atom of a completely different element. For example, if one proton was to be removed from the nucleus of the atom for the element of Krypton that atom will be an atom of the element bromine. The number at the bottom of the square represents the number of particles present in the atom's nucleus of that element. This is known as the atomic weight. For example, the atomic weight for the element Krypton is 83.80.

The number of positively charged particles in atoms of a given element?
Positive charged particles in atomic nucleus - protons. Number of protons = atomic number (The number of a given element in the Mendeleev table)
