carbon exists as 3 naturally isotopes c12 c13 c14 as he number of neutrons increase in the isotope the nuclear charge
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.
an electrically neutral atom is just an atom. Atoms with more or fewer electrons (negatively charged) compared with their protons (which determines the element) are considered ions.
The magnesium atom is electrically neutral.
The number of protons and electrons is equal.
An electrically neutral atom is one that has an equal number of protons and electrons.
All atoms are electrically neutral. If an atom gains or loses an electron, we call it an "ion" rather than an atom.
Because an electrically neutral atom has an equal number of protons and electrons.
Any atom is neutral in the normal state.After loss or gain of electrons an atom become electrically charged.
An atom has the same number of positive protons and negative electrons so the charges balance out to zero
Na+
An alumimium atom is electrically neutral and it is an isotope of aluminum.
All ions differ from an electrically neutral atom in that they are missing or have gained one or more electrons. A S2- atom has 2 less electrons than a neutral atom.
