Always the Atomic Number = Number of Protons

If electrically neutral, Atomic Number = Number of Electrons = Number of Protons

How many electron are in an neutral atom of sodium?

11 electrons in a neutrally charged atom of sodium . It is the same number as the number of protons and the Atomic Number. However, the sodium ion (NOT Atom) has lost one electron , so there are now 11 protons(+), and 10 electrons(-). Hence 11(+)10(-)= 1(+) Hence the sodium ion is written as 'Na(+)'.


What is the charge of an atom that has an equal number of protons and electron?

It is a neutral atom


In a atom is the electron number the same proton number?

Yes, provided the atom is electrically neutral.

Why number of electron are equal to the number of proton?

because an atom is electrically neutral


The number of protons in a neutral atom is equal to the number of what?

In a electrically neutral atom, the number of positive charges in the atom's nucleus (with one charge being held on each proton in the nucleus), is balanced out by the number of negative charges present in the electron cloud round the nucleus (with one charge being held on each electron in the cloud). This means that in a neutral atom the number of Protons = the number of Electrons.


Give the electron configuration for a neutral atom of chlorine?

The electron configuration for a neutral atom of chlorine is 1s2 2s2 2p6 3s2 3p5. Chlorine has 17 electrons, and this configuration indicates the distribution of those electrons in its various energy levels.


Where there is the same number of proton's as electron's the charge on the atom is considered?

neutral


What number of electrons in a neutral atom of an element will be equal to?

The amount of electrons is balanced by the same amount of protons in a neutral atom, such as for the neutral hydrogen atom; it has 1 proton and 1 electron.


How many electrons does a neutral hydrogen atom have?

Hydrogen is a non metal element. There are 1 electrons in a single atom.


What is the number of electrons in an atom that is neutral atom with 30 protons and 34 nuetrons?

the no of electrons in a neutral atom is equal to the total no of proton so no of electron is equal to 30.


How many protons are there in the ions?

An Ion is:either positive ion that is a neutral atom with an electron or more stripped off from its electron orbits, ora negative ion that is a neutral atom acquiring an electron or more to its electron orbits.Accordingly, the number of protons in the nucleus is not affected by the ionization process. The number of protons in any ion of an element is the same number corresponding to the atom structure of the atom of that element.
