What is the number of protons in the nucleus or the number the electrons in the energy levels called?
The number of protons in the nucleus is called the atomic number and is equal to the number of electrons in a neutral atom.
How many valence electrons does a neutral Be atom have?
It depends on the atom.Atoms may have up to three energy levels, or layers of electrons, although some elements, such as helium, have only one. If an atom has one energy level, its valence electrons may total up to only two. If it has two or three energy levels, It may have up to eight total valence electrons. An atom is neutral when it has the greatest possible number of electrons.
How many protons are in an electrically neutral oxygen atom?
8
Does an element's number of valence electrons equals the element's number of protons?
Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.
Is it true that to find the total number of electrons available for bonding in a positive ion you should add the ion charge to the total number of valence electrons of the atoms present?
No, you should subtract the ion charge from the total number of valence electrons of the neutral atom to find the total number of electrons available for bonding in a positive ion. This is because a positive ion has lost electrons compared to the neutral atom.
How many valence electrons does a neutral atom of silicon have?
A neutral atom of silicon will have 4 valence electrons. The amount of valence electrons that a neutral atom will have can be found by the atoms group number in the periodic table.
How do you determine the valence electrons of aluminium?
In the neutral atom of a chemical element number of electrons= number of protons=atomic number.
How many valence electrons does a neutral magnesium atom have?
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
How many inner electrons does Br have?
Bromine (Br) has 36 inner electrons. This can be calculated by subtracting the number of valence electrons (7) from the total number of electrons in the neutral atom of bromine (usually 43).
How many valence electrons are in S-32?
Sulfur (S) has 6 valence electrons in its neutral state. Sulfur-32 (S-32) would have the same number of valence electrons because the number of protons (which determines the element's identity) remains the same in isotopes.
What the total number of valence e OF2?
The total number of valence electrons in OF2 is 18. This is calculated by adding the number of valence electrons for each atom (O has 6 and F has 7) and considering that there are two fluorine atoms linked to one oxygen atom in the molecule.
What is the number of valence in hydrogen sulfate?
Hydrogen sulfate (HSO4-) has 7 valence electrons. This is calculated by adding the number of valence electrons in sulfur (6 electrons) and hydrogen (1 electron), then subtracting one due to the negative charge on the ion.
What is the number of protons in the nucleus or the number the electrons in the energy levels called?
The number of protons in the nucleus is called the atomic number and is equal to the number of electrons in a neutral atom.
How many valence electrons in U 238?
Uranium has two valence electrons; possible valences are 6, 5, 4, 3, 2, 1.
How many core electrons in nitrogen?
Nitrogen has 2 core electrons and 5 valence electrons. If you remember, nitrogen has an atomic number of 7. When an atom is neutral it has an equal number of protons and electrons. Therfore, the overal number of electrons is 7. The definition of core electrons is, electrons in their most inner shell, On the other hand valence electrons are electrons in the outermostshell. When looking at a periodic table you see that there is a total# of 5 valence electrons. In order to figure out the core number you subtract the total number of electrons(atomic #) - Valence # of electrons. I hope this helped :)
How many valence electrons does a neutral Be atom have?

An atom is neutral when it has the greatest possible number of electrons.
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
