An atom is stable because of a balanced nucleus that does not contain excess energy. If the forces between the protons and the neutrons in the nucleus are unbalanced, then the atom is unstable. Stable atoms retain their form indefinitely, while unstable atoms undergo radioactive decay. Most naturally occurring atoms are stable and do not decay.Know More
The nucleus of an atom is made up of protons and neutrons. The forces inside the nucleus of a stable atom are balanced because the nucleus contains the proper number of protons and neutrons. These atoms are theoretically resistant to all forms of decay except proton decay, which is a hypothetical form of decay that has never been observed in a laboratory or in nature.
Unstable atoms are radioactive and decay after a certain amount of time. Different unstable atoms decay through different processes, such as the ejection of a proton or a neutron; the conversion of a proton to a neutron or a neutron to a proton; and the emission of the excess energy in the form of photons. In many cases, the resulting atom is still unstable. This atom then decays again to a new atom. The process continues in a decay chain until a stable form is reached.Learn more about Atoms & Molecules
The three components that make up an atom are protons, electrons and neutrons. Protons possess a positive electrical charge, electrons are negatively charged and neutrons have no electrical charge at all.Full Answer >
An isotope is an atom that contains a different number of neutrons than its base chemical element. Each element is defined by its respective number of protons. The atomic number of an element refers to its proton count and establishes that particular element within the periodic table.Full Answer >
Ionic compounds are formed when electrons are transferred from one atom to another, while covalent compounds are formed when both atoms share their electrons, resulting in no loss or gain of electrons for either atom, according to HyperPhysics. The atoms of covalent bonds are bound more tightly and form more stable molecules when compared to the atoms of ionic bonds, which show attraction to other nearby atoms.Full Answer >
There are three primary components inside an atom: neutrons, electrons and protons. The neutrons have no charge, while the protons have a positive charge and electrons have a negative charge. The neutrons and protons exist in a dense center area called the nuclei, while the electrons exist in another space, called orbitals, around the nuclei.Full Answer >
