NGSS.HS-PS1-1

NGSS.HS-PS1-3

Force of attraction that holds together two atoms that share a pair of electrons. The shared electrons are attracted to the nuclei of both atoms

• alloy bond

• reaction bond

• Chemical bond

• Covalent bond

Chemical reaction that releases energy because it takes less energy to break bonds in the reactants than is released when new bonds form in the product.

• equilibrium

• nonpolar

• endothermic reaction

• exothermic reaction

NGSS.HS-PS1-4

Chemical reaction that needs a constant input of energy to continue because it takes more energy to break bonds in the reactants than is released when new bonds form in the products.

• equilibrium

• nonpolar

• endothermic reaction

• exothermic reaction

NGSS.HS-PS1-4

A covalent bond where electrons are shared equally

• equilibrium

• nonpolar

• endothermic reaction

• exothermic reaction

A point in a chemical reaction at which the forward and reverse reactions occur at the same rate

• equilibrium

• nonpolar

• endothermic reaction

• exothermic reaction

• equilibrium

Substances that are produced in the reaction

• reactants

• product

• chemical reaction

• equilibrium
