strontium
Assuming the question is "do all isotopes of an element form the same type of ions" then the answer is YES.The chemistry of an element is determined by the number of protons and electrons.Isotopes of an element only differ one from another by the number of neutrons present in the nucleus, the chemistry is not affected, and they will form the same ions.An example is chlorine. The two common isotopes are 35Cl and 37Cl which are both present in nature. Both form Cl- ions.
The element with 18 neutrons forms 1- charged ions, as it would gain one electron to achieve stability, making it a halogen. Therefore, the element is likely to be chlorine (Cl), as it has two naturally occurring isotopes with 18 and 20 neutrons.
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
The number of protons defines an element - the number of neutrons isn't needed to find the identity of the element. All ions and isotopes with 44 protons is ruthenium. However, with the information about the neutrons, we know the specific isotope: 101Ru.

oxygen
Positive ions
Try "the proton" (change the electrons and you get ions, change the neutrons and you get an isotope.)
In ionic bonds, an element donates electrons to a more electronegative element to from ions. The prior element makes positive ions where the latter makes negative. Then these ions form electrostatic bond to form a crystalline lattice. Therefore ionic compounds have ionic bonds in them.
Chloride ions would form elements with ions of metallic elements. For example, with sodium ions, chloride ions form sodium chloride.
Oxygen is the element that reacts to form oxide ions. Oxygen typically gains two electrons to become the oxide ion (O2-).
An isotope is an element that has lost or gained neutrons. Isotopes have the same amount of protons and electrons but have a different number of neutrons. The less neutrons the lighter the isotope, the more neutrons, the heavier the isotope. An ion is an element that has lost or gained electrons. Ions have more or less electrons than protons and have a normal amount of neutrons. The more an atom has the more negative it is, the less the more positive it is.
