WebAug 31, 2024 · An ion is an atom or group of atoms in which the number of electron s is different from the number of proton s. If the number of electrons is less than the number of protons, the particle is a positive ion, also called a cation. How many neutrons are in an ion? Since it has a charge of +2 , this ion must contain 80 electrons. WebSep 6, 2016 · For the polyatomic ions only, determine their total charge. Taking the potassium permanganate example K M n O X 4: You have potassium, manganese and oxygens which could (at first assumption) all exist as part of polyatomic ions. However, deduce potassium from that above list. It does not form polyatomic ions.

How can one determine the charge of a polyatomic ion?

WebAt your level it's enough to know that metals generally form positive ions and non-metals form negative ions. The size of the charge is equal to the number of electrons needed to … WebOct 29, 2015 · In other words, the difference between the number of protons and the number of electrons gives you the atom's net charge. net charge = no. of protons −no. of electrons. In this case, you have. +1 = Z − 104 ⇒ Z = 104 +1 = 105. Therefore, your atom has 105 protons and 157 neutrons in its nucleus, which means that it has a mass number equal to. inception personages
