None. Electrons are found in energy levels outside the nucleus, not in it. An atomic number of 20 tells you there are 20 protons in the nucleus of an atom, and 20 electrons in energy levels (or shells or orbitals depending on which model of the atom you are using) outside the nucleus.
What else can I help you with?
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
What does the atomic number describe about an atom?
The number of protons in the nucleus of an atom
What number of an element can be used to determine the number of electrons in an atom?
The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.
The total number of electrons surrounding the nucleus of an atom of Al is?
The number of electrons in an aluminum atom is 13, as it has an atomic number of 13. This means that there are 13 electrons surrounding the nucleus of an aluminum atom.
What is the difference of atomic number and atomic mass?
atomic number is the number of protons in the nucleus or electrons around the nucleus in an atom that is not ionized. atomic mass is the sum of the number of protons and the number of neutrons in the nucleus.
Are the number of electrons in the nucleus of an atom that element's atomic number?
There are no electrons in the nucleus of an atom, the electrons are in the orbitals around and outside the nucleus.There are no electrons in the nucleus of an atom, the electrons are in the orbitals outside and around the nucleus.
The protons in the nucleus of an atom is called the?
the no. of protons or the no.of electrons inthe nucleus ofan atom is called the atomic number of that atom.
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
Atomic number equals the number of?
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
The atomic number is the number of what in the nucleus?
It is the number of protons and electrons in an atom
How can you determine the number of electrons in a atom?
The number of electrons in an atom can be determined by looking at the atomic number of the element on the periodic table. The atomic number represents the number of protons in the nucleus of an atom, which is equal to the number of electrons in a neutral atom.
The atomic number of an atom indicates the number of?
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
What does the atomic number describe about an atom?
The number of protons in the nucleus of an atom
What number of an element can be used to determine the number of electrons in an atom?
The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.
The atomic number is the same as the number of these particles?
In any atom, the number of protons will equal the number of electrons, but only in a neutral atom. Remember that most atoms loan, borrow or share electrons, so the number of protons will not be equal to the number of electrons in all cases. In review, only in a neutral atom will the number of protons equal the number of electrons.
What does the atomic number of an atom reveal the number of?
it tells you the amount of electrons the atom has orbitting the atom and the nucleus
The total number of electrons surrounding the nucleus of an atom of Al is?
The number of electrons in an aluminum atom is 13, as it has an atomic number of 13. This means that there are 13 electrons surrounding the nucleus of an aluminum atom.
