An element has it's protons balanced with electrons. The ion of an element is unbalanced: either positively charged if it lost an electron or negatively charged if it gained one.
What is the difference between ammonia gas and an ammonium ion?
an electron
Nitrate ion is NO3-1 while Nitride is N-3.
a compound is more then one element
The difference is in the number of electrons they have. In a neutral atom, the number of electrons is the same as the number of protons (or atomic number) for that element. In an ion, this is not the case, with either less electrons (an overall positive charge) or more electrons (an overall negative charge) than he neutral atom
an ion is when an element loses or gains one or more electrons. an isotope is when a element loses or gains one or more neutrons. when one or more proton(s) is/are gained or lost, it becomes a different element.
What is the difference between ammonia gas and an ammonium ion?
Basically, an ion is when the charge of an element is not what it would normally be. So if you took oxygen, which is naturally a -2 charge, and it lost an electron, it would become an oxygen ion with a charge of -1.
molecules
An ion is an atom with electrical charge, a cation or an anion.Isotopes are atoms of the same element but having different number of neutrons.
The fluoride ion is the ion formed by the element fluorine
an electron
Ions are charged.
Nitrate ion is NO3-1 while Nitride is N-3.
Chlorite is ClO2- ion whereas chloride is Cl- ion
biology
The ion biphosphate is (HPO4)2-.The ion pyrophosphate is (P2O7)4-.
