Charge
The positively charged particle of an atom, located in the nucleus
What is a proton
Any substance that cannot be broken down into a simpler one by a chemical reaction
What is an element?
A chemical bond in which a hydrogen atom of one molecule is attracted to an electronegative atom, especially a nitrogen, oxygen, or flourine atom, usually of another molecule
What is a hydrogen bond?
a substance produced in a chemical reaction
What are products?
a biological compound that is not soluble in water, e.g. a fat
What is a lipid?
the negatively charged particle that orbits the nucleus of an atom
What is an electron?
A substance formed by the chemical combination of elements in fixed proportions
What is a compound?
A chemical bond formed by the sharing of one or more electrons, especially pairs of electrons, between atoms.
What is a covalent bond?
a substance that reacts with another in a chemical reaction
What are reactants?
an organic compound, either RNA or DNA, whose molecules are made up of one or two chains of nucleotides and carry genetic information
What is a nucleic acid?
The neutral particle of an atom that is located in the nucleus. Has a mass equal to a proton.
What is a neutron?
a substance consisting of two or more substances mixed together and uniformly dispersed, most commonly the result of dissolving a solid, fluid, or gas in a liquid
What is a solution?
What is an ionic bond?
a measure of acidity or alkalinity in which the pH of pure water is 7, with lower numbers indicating acidity and higher numbers indicating alkalinity.
What is pH?
the state in which the particles of a substance are mixed with a fluid but are undissolved
What is suspension?
The number of protons in the nucleus of an atom of an element and its isotopes
What is the atomic number/mass?
a substance that dissolves another to form a solution
the molecular force between particles within a body or substance that acts to unite them
What is cohesion?
the smallest physical unit of a substance that can exist independently, consisting of one or more atoms held together by chemical forces
What is a molecule?
a biological compound containing carbon, hydrogen, and oxygen that is an important source of food and energy
What is a carbohydrate?
Each of two or more forms of a chemical element with the same atomic number but different numbers of neutrons
What is an isotope?
The substance dissolved in a given solution
What is a solute?
the molecular force of attraction in the area of contact between unlike bodies that acts to hold them together
What is adhesion?
the smallest portion into which an element can be divided and still retain its properties
What is an atom?
a group of atoms that reacts as a single unit and determines the properties and structure of a class of compounds
What is a functional group?
