cell correct answerfundamental, basic unit of life
Matter correct answeranything that occupies space and has mass
Subatomic Particles of Atom correct answerprotons, neutrons, and electrons
Electrons correct answerSubatomic particle with a negative charge. Found outside the nucleus in the "shells". Have no mass.
Neutrons correct answerSubatomic particle with no/neutral charge. Found inside the nucleus. Mass of 1 amu.
Protons correct answerSubatomic particle with positive charge charge. Found inside the nucleus. Mass of 1 amu.
ion correct answeratom with more or less protons than electrons
elements correct answerdifferent types of atoms (92 naturally occurring on earth) periodic table correct answerchart organizing elements
atomic number correct answernumber of protons in an atom is denoted by
atomic mass correct answerthe mass of an atom
molecule correct answera more complex entity created by 2 or more atoms combined by covalent bond.
Chemical bonds correct answerattractions between atoms that hold atoms and molecules together
types of chemical bonds correct answercovalent bonds, ionic bonds, and hydrogen bonds
Covalent Bond correct answerstrongest bond. occurs between atoms in the same molecule. Electron pairs are shared, creating a strong bond between atoms
Ionic Bond correct answermoderate strength. occurs between atoms in the same molecule (i.e., between the ions). Electrons transfer from one atom to another, resulting in a moderately strong electrostatic attraction between oppositely charged ions.
Hydrogen Bond correct answerWeak Occurs between atoms in different molecules or parts of molecules. Weak electrostatic attraction between areas of molecules with opposite partial charges
cations correct answerpositively charged ions (lose electrons)
anions correct answernegatively charged ions (gain electrons)
