Numbers of electrons in a neutral atom can be determined from its atomic number because in such an atom, number of protons will be equal to the number of electrons. In non-neutral atoms you have to subtract the charge from atomic number to get the number of electrons.
For example-
If you take O(-). Number of electrons = A.N. - charge
= 8 - (-1)
= 9
What else can I help you with?
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.
What are the number of electrons present in a neutral barium atom?
The barium atom (neutral) contain 56 electrons.
How do you determine the number of electrons in an atom?
The number of electrons in an atom is determined by the atomic number of the element, which is the same as the number of protons in the nucleus. Electrons are negatively charged particles that balance the positive charge of protons in an atom.
What can be determined if only the atomic number of an item is known?
the total number of protons and the total number of electrons in the atom
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
What is the total number of electrons found in an atom of phosphorus?
An atom of phosphorus has 15 electrons in total. This can be determined based on its atomic number, which is 15.
What subatomic particle is responsible for whether or not an atom will be an ion?
Ionic charge is determined by the number of electrons in the atom. A neutral atom has the number of electrons equal to the number of protons in the nucleus. An ion is formed when there is a surplus or deficit in electrons
How can you determine the number of valence electrons an atom has?
The valence is determined experimentally.
How many electrons are there in an atom?
An atom contains an equal number of electrons and protons, which balances out the charge to neutral. The number of electrons in an atom is determined by its atomic number, which is the same as the number of protons in the nucleus.
How many electrons can occupy each shell in an atom?
The number of electrons that can occupy each shell in an atom is determined by the formula 2n2, where n is the shell number.
How many core electrons are in a ground state atom of bromine?
A ground state atom of bromine has 28 core electrons. This can be determined by subtracting the number of valence electrons in a neutral bromine atom (7) from the total number of electrons in a bromine atom (35).
What determines the neutrality of an atom?
The neutrality of an atom is determined by the balance between the positive protons in the nucleus and the negative electrons surrounding it. If the number of protons equals the number of electrons, the atom is neutral.
