Sc3+. Scandium has an atomic number of 21, in Sc3+ the number of electrons is 3 less as it is positively charged.
This cation has 24 electrons.
The element is vanadium (V) because it has 23 protons. With 18 electrons and a net charge of 3 plus, it would have lost 3 electrons, resulting in a net charge of +3. The number of neutrons (28) does not affect the charge or identity of the element.
By losing electrons.
Atomic Number: This is the number of protons an element has. Answer: 26 Atomic Mass: Ignoring electrons, which are incredibly small and don't have much of an effect on the mass... This is the number of protons plus the number of neutrons Answer: 56 (26 protons + 30 neutrons) Net Charge: Protons are positive and electrons are negative. The net charge can be found by subtracting the number of electrons from the number of protons. 0 is neutral. Answer: +3 (26 protons - 23 electrons)
Electrons. Electrons carry a negative charge so when one is removed from the atom the atom gains a net positive charge.

A crystal of salt consists of electrons and positive ions. How does the net charge of the electrons compare with the net charge of the ions
By losing electrons.
The net charge will be negative, since electrons have a negative charge and protons have a positive charge. When 5 electrons (-5) combine with 3 protons (+3), the net charge will be -2.

Electrons. Electrons carry a negative charge so when one is removed from the atom the atom gains a net positive charge.
Look at the periodic table. You see that the element that has 16 protons is Sulfur. Electrons have a single negative charge, while protons have a single positive charge, so an ion with 2 more electrons than protons will have a charge of 2-. So, the symbol of the ion would be S2- .
The net charge of an atom is determined by the number of protons and electrons. Protons have a positive charge, while neutrons are neutral and do not contribute to the charge. If there are 11 protons, the atom has a positive charge of +11. If there are no electrons mentioned, we can assume it has 11 electrons to remain neutral, resulting in a net charge of 0. However, if there are no electrons, the net charge would be +11.
The net charge of an atom or ion is determined by the balance of protons and electrons. Protons, which have a positive charge, and electrons, which have a negative charge, contribute to the overall charge of the atom. To calculate the net charge, subtract the number of electrons from the number of protons: ( \text{Net Charge} = \text{Protons} - \text{Electrons} ). If an atom has more protons than electrons, it is positively charged (cation), while more electrons than protons result in a negative charge (anion).
The net charge of an oxygen ion is typically -2. In its neutral state, oxygen has 6 protons and 6 electrons, giving it a net charge of 0. When it gains 2 electrons to become an ion, it carries a net charge of -2.
A net charge results when an atom gains or loses electrons. If it loses electrons, it gains a positive charge, if it gains them, it gains a net negative charge.
