Which element has 16 neutrons, 15 protons, and 15 electrons? A charged atom is called How can a charged atom (an ion) attract a neutral atom? What is the mass number of a proton? What property of ions allows them to conduct electricity?
Atoms are the purest form of matter. They consist of protons, neutrons, and electrons. The periodic table lists all of the different types of atoms that are known to exist and are known as elements. Answer and Explanation: An atom that has more protons than electrons is called a cation. ...

The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that ...

Generally, mass is defined as the measure of how much matter an object or body contains - the total number of sub-atomic particles (electrons, protons and neutrons) in the object. If you multiply your mass by the pull of earth's gravity, you get your weight. So if your body weight is...
In all atoms, the number of protons and the number of electrons is always the same. So nitrogen has 7 protons and 7 electrons, calcium has 20 protons and 20 electrons, and tin has 50 protons and 50 electrons. The number of neutrons is very roughly the same as the number of protons, ...
