For a neutral atom they must have equal numbers of protons and electrons. The atomic number is the number of protons in an atom of an element. Find the atomic number by looking at the Periodic Table of elements.
In a electrically neutral atom (not an ion), the number of electrons is the same as the number of protons. Since a proton has a positive 1 charge and an electron has a negative 1 charge, the number of electrons has to be the same as the number of protons if the atom is neutral.

For ions, the charge of the atom must be taken into account. For example, if the atom has a -3 charge, it has three more electrons than protons. Therefore, the number of electrons is the number of protons in the atom, plus three more electrons for the ion to have a -3 charge.
It is just the same as the number of protons, and Atomic Number. :)
Electrons are the same thing as protons so, you would look at the first # in the square "Atomic Mass" andthere's your awnser.
In a neutral atom the number of electrons is equal with:
- the number of protons
- the atomic number in the periodic table
The number of electrons in a neutral atom is the same as the atomic number of the atom and is listed for each element in the periodic table found in any basic chemistry text book.
i dont know
The atom needs to have the same number of electrons as it has protons.
the number of sinqle electrons in the atom
Because an atom of element has the same number of electrons as of protons and the number of protons in an atom is the same as the atomic number of the atom, the answer to this is whichever element has the highest atomic number yet synthesized.
The electron. The electron is has a negative charge. The more electrons that are in a valence shell of the atom the more negative the atom will be.
Under normal conditions, i.e. non-ionic, the number of protons is equal to the number of electrons.
because an atomic number is the same as the number of electrons in an atom (not ion)
Look up the atomic number of the element. The atomic number is the number of protons, in a neutral atom this is the same as the number of electrons.
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
the atomic mass number is the number of protons/electrons in an atom
Reference the atomic number of the atom on the periodic table. The electron count is generally equal to the number of protons
You can only be sure of the number of electrons if the element is electrically neutral. If an element is electrically neutral, then the number of electrons is the same as the number of protons which is the atomic number of the element. For instance an electrically neutral atom of carbon, there are 6 electrons because there are 6 protons in a carbon atom.
to calculate the formal charge:Take the number of valence electron the neutral atom would have (found on the periodic table) and subtract it from the number of electrons in lone pairs +1/2 of the number of electrons in bonds
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
The number of electrons in a neutral atom is the same as the atomic number of the atom and is listed for each element in the Periodic Table found in any basic chemistry text book.
A positive ion is an atom which is positively charged, which means it has less electrons than protons (the number of protons in an atom equals the atom number, so you should be able to calculate the number of electrons knowing if it's single or double positively charged).
An atom's atomic number is the number of electrons.
