What is the Law of Conservation of Mass?️️The law that states that mass cannot be created or destroyed in ordinary chemical and physical changes. What is the Law of Definite Proportions?️️The law that states that a chemical compound always contains the same elements in exactly the same pr...

chemical bond️️the attractive force that holds atoms or ions together ionic bonding️️a force that attracts electrons from one atom to another, which transforms a neutral atom into an ion. covalent bonding️️a bond formed when atoms share one or more pairs of electrons nonpolar-covalen...

Democritus️️Matter is made of "indivisible parts" he called atomos "meaning cannot be cut" Democritus️️Because of his ideas, we still call these particles atoms Dalton️️Proposed that atoms are small indivisible spheres Dalton's Atomic Model️️Billard Ball model and was hard sp...

Ionic Bond️️Force of attraction between two oppositely charged ions formed by one particle losing electrons and another gaining electrons; formed when one atom takes an electron from another atom--ions are the result (one positive, one negative)--they stick together because of opposite charge...
