The number of valence electrons in an atom determines its ability to form ions. Atoms that have few valence electrons tend to lose them to form positive ions, while atoms with many valence electrons tend to gain electrons to form negative ions. The ionic charge of an ion is related to the number of electrons gained or lost during the formation of the ion.
MgOMagnesium: 2 Valance Electrons (Charge is +2)Oxide: 6 Valance Electrons (Charge is -2)Hint: Oxide has a charge of -2 and so does Oxygen. Check the periodic table for the elements that have a -2 charge (group 16) and you will find oxygen as the first element in that group. Periods define how many energy levels the element has, just so you know. Oh and this is ionic.Hope this helps!
They are equal.
Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond, while core charge refers to the positive charge in the nucleus of an atom taking into account the shielding effect of inner electrons. Generally, atoms with higher core charge tend to have higher electronegativity as they have a stronger pull on electrons due to their increased positive charge in the nucleus.
In a polar bond, there is an unequal sharing of electrons between atoms due to differences in electronegativity, resulting in a partial positive and partial negative charge. This creates a dipole moment. In a nonpolar bond, there is equal sharing of electrons between atoms resulting in no dipole moment.
In a chemical reaction, conjugate redox pairs are related because they involve the transfer of electrons between them. One species loses electrons (oxidized) while the other gains electrons (reduced). This exchange of electrons allows the reaction to proceed and maintain charge balance.
Protons have a positive charge, while electrons have a negative charge. The relationship between the charges of a proton and an electron is that they are equal in magnitude but opposite in sign.
Manganese has two electrons in its valance shell, Mn is a metal so it has a tendency to give away electron (2 of them, so the charge is -2) while Bromide is a non-metal and it adopts electrons to complete its valance shell and has a positive two charge. so the Mn gives away 2 electrons and Br gains 2 electrons so the overall charge of the compound is zer0. MnBr.

Protons, Neutrons and Electrons Protons: they have a positive charge and they are inside the nucleus Neutrons: they have a neutral charge and they are also inside the nucleus Electrons: They have a negative charge and orbit outside the nucleus within valance rings :)
The relationship between positive and negative electric charges is in their number of electrons. This causes them to be attracted or repel each other based on this charge.
In a neutral atoms, the numbers of protons and electrons must be the same, because each of these particles has the same magnitude of electrical charge.
CH3COO- has 8 valence electrons. The carbon contributes 4, each hydrogen contributes 1, and the extra electron from the negative charge contributes 1.
Magnesium as an atom has two valance electrons. To complete it's octet, it must lose two electrons. Losing two electrons will make Mg have 12 protons and 10 electrons therefore having a +2 charge.
Electrons have a negative charge and protons have a positive charge.
