How many protons are in an ion that has 86 electrons and a -1 charge? How many protons are in an ion that has 10 electrons and a -1 charge? How many protons and electrons are needed to make an ion of charge +1? How many electrons are in a chlorine atom that has a charge of ...
The charge of an atom is determined by the number of protons and electrons in the atom. Neutral atoms have an equal number of protons and neutrons to balance out the positive charge of the protons and the negative charge of the electrons....
How Many Neutrons and Protons Can Get Along? Maybe 7,000Clara Moskowitz, SPACE.com
How Many Protons? The atomic number on the Periodic Table identifies the number of protons in any atom of that element. Copper, atomic number 29, has 29 protons. Finding the atomic number of an element reveals the number of protons.
Question: How many chloride ions are present in a 12.4-gram sample of calcium chloride? Ions: Ions are charged substances that posses more electrons than protons. We can form ions from the loss or gain of electrons in an oxidation reduction reaction. Ionic compounds can be formed...
