The number of electrons is equal to the number of protons in that atom. An easy way to view that is with the Bohr Model.
To determine the number of valence electrons in an electron configuration, look at the outermost energy level of the atom. The number of electrons in this level is the number of valence electrons.
To determine the number of valence electrons from an electron configuration, look at the highest energy level (n value) of the electrons in the configuration. The number of electrons in this highest energy level is the number of valence electrons.
To determine the number of valence electrons, you look at the group number of an element on the periodic table.
To determine the number of electrons in an element, you can look 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.
To determine the number of electrons in an element, you can look at the element's atomic number 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.
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.
Electrons determine the chemical properties.
To determine the number of valence electrons in an atom based on its electron configuration, look at the outermost energy level of the atom. The number of electrons in this energy level is the number of valence electrons.
An ion is formed when an atom gains or loses electrons, giving it a positive or negative charge. You can determine if an atom is an ion by looking at its number of electrons compared to its atomic number. If the number of electrons is not equal to the number of protons, the atom is an ion.
In a neutral atom the total number of electrons is equal to the number of protons and atomic number.
the number of electrons of an atom is the same as it's atomic number
subtract the group number from the atomic number
