16 protons and 18 electron
It indicates the protons. Periodic table is based on atomic number.
The atomic number indicates the number of protons (19) and electrons (19).
The atomic number of an element represents the number of protons in the nucleus, which determines its unique identity on the periodic table. It also indirectly indicates the number of electrons in a neutral atom of that element.
The atom chlorine usually has 17 protons and 17 electrons. However, the ion Cl-1 indicates that it has gained one electron, so it now has 17 protons and 18 electrons.
AnswerThere are 30 electrons, 25 neutrons, 30 protons,the atomic number is 30 and the atomic mass is about 65.
A sulfide ion has 16 protons and 18 electrons. The -2 charge indicates that the ion has gained two electrons, giving it two more electrons than protons.
The sulfide ion (S²⁻) has 16 protons and 18 electrons. This is because the element sulfur (S) normally has 16 protons and 16 electrons, but by gaining two extra electrons to achieve a stable electron configuration, it becomes the sulfide ion with 18 electrons.
A sulfide ion (S2-) has 16 protons. This is because the sulfide ion carries a charge of -2, indicating that it has gained two extra electrons, and thus has 16 protons in its nucleus as the number of protons always determines the element.
The charge on an ion indicates the imbalance between the number of protons and electrons. If an ion has a positive charge, it has more protons than electrons. If it has a negative charge, it has more electrons than protons.
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
The atomic number indicates the number of protons or number of electrons in the case of a neutral atom.
It indicates the protons. Periodic table is based on atomic number.
The atomic number indicates the number of protons (19) and electrons (19).
The number of protons in an atom of an element is equal to the number of electrons and is referred to as the ATOMIC NUMBER of that element.
Vanadium has 23 protons. The atomic number is the same as the number of protons.
An element's atomic number indicates the number of protons it has in the nucleus. In this case, since polonium's atomic number is 84, it has 84 protons. In a neutral atom, the number of protons is the same as electrons. This is because the positive charge of the protons in the nucleus must be balanced with by the negative charge of the electrons. Therefore, in this case, because polonium has 84 protons, it has 84 electrons.
The atomic number of an element represents the number of protons in the nucleus, which determines its unique identity on the periodic table. It also indirectly indicates the number of electrons in a neutral atom of that element.
