Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma).
Sulfur, the tenth most abundant element in the universe, has been known since ancient times. Sometime around 1777, Antoine Lavoisier convinced the rest of the scientific community that sulfur was an element.
The halogens are five non-metallic elements found in group 17 of the periodic table. The term "halogen" means "salt-former" and compounds containing halogens are called "salts".
usually ductile refers to the ability of metal to be drawn into a wire like how a piece of chewing gum gets smaller in diameter when you stretch it out between your mouth and fingers
- Liquid is one of the four fundamental states of matter (the others being solid, gas, and plasma), and is the only state with a definite volume but no fixed shape. A liquid is made up of tiny vibrating particles of matter, such as atoms, held together by intermolecular bonds.
Chemical changes involve chemical reactions and the creation of new products. Typically, a chemical change is irreversible.
Potassium is an essential nutrient used to maintain fluid and electrolyte balance in the body. A deficiency in potassium causes fatigue, irritability, and hypertension (increased blood pressure).
- The alkaline earth metals are a series of elements comprising Group 2 (IUPAC style) (Group IIA) of the periodic table: beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba) and radium (Ra).
Translucent materials allow light to pass through them, but they diffuse the light in a way that make objects on the opposite side appear blurred. Examples of translucent materials are frosted glass, oil paper, some plastics, ice and tissue paper
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition
