Study Notes
Atoms and Elements Study Notes
-
Atom: The fundamental unit of an element, retaining the element's characteristics.
-
Proton: Positively charged subatomic particle found in the nucleus of an atom.
-
Nucleus: The core of an atom, containing protons and neutrons; acts as the control center in cells.
-
Neutron: A subatomic particle with the same mass as a proton but lacks electric charge.
-
Electron: Negatively charged subatomic particle that orbits the nucleus and has negligible mass.
-
Atomic Number: Indicates the number of protons in an atom, determining the element's identity.
-
Element: A pure substance consisting only of one kind of atom, distinguished by its atomic number.
-
Metal: A class of elements known for their ability to conduct heat and electricity; typically malleable.
-
Nonmetal: Elements that do not conduct electricity well and are generally not malleable.
-
Periodic Table: A systematic arrangement of elements organized by increasing atomic number.
-
Compound: A substance formed when two or more different elements chemically bond together.
-
Melting Point: The specific temperature at which a solid transitions into a liquid.
-
Boiling Point: The temperature at which a liquid becomes a gas.
-
Plasma: A state of matter consisting of charged and uncharged atoms alongside free electrons.
-
Isotopes: Variants of the same element with the same number of protons but differing numbers of neutrons.
-
Fusion: The process of combining two or more entities into a single form.
-
Molecules: The smallest unit of a substance, either consisting of one type of atom (element) or multiple atom types (compound).
-
Malleable: A property of materials that allows them to bend and be shaped easily without breaking.
