Atoms that have gained or lost electrons are called ions. If an atom gains electrons, it is called an anion; if it loses electrons, it becomes a cation. Through the gain or loss of electrons, atoms are no longer neutral.Know More
When atoms gain electrons, they become negatively charged. Atoms losing electrons become positively charged. In a neutral atom, the number of electrons orbiting the nucleus equals the number of protons in the nucleus of the atom. Protons are the positive particles in an atom, while electrons are the negative ones. A neutral atom has the same number of positive as negative charges. With the positive and negative charges canceling each other out, a neutral atom has no net charge.
With the gain or loss of electrons, the balance of protons and electrons is shifted. Either the atom contains more protons than electrons or more electrons than protons, resulting in the atom gaining a net charge.Learn more about Atoms & Molecules
There is no universal net charge for atoms. An atom's net charge is determined by comparing the number of protons and electrons that are in each atom.Full Answer >
A molecule is made up of two or more atoms of the same element or compound, or different elements or compounds, that are chemically bound together. A molecule is a quantity of a substance that can be measured by a chosen unit. Molecules are extremely small particles.Full Answer >
In nuclear science, a pure element is a chemical element that consists of a singular stable isotope – that is, atoms of the same element. Examples of a pure element are gold, aluminium and fluoride.Full Answer >
To determine an element's molar mass, it is necessary to add together the weight of all of the atoms present in the sample. The atomic weight of an element is printed inside the element's box on the periodic table. The molar mass is the atomic weight multiplied by the number of atoms per mole.Full Answer >
