Unit 5 Science

made of protons and neutrons in a nucleus and electrons orbiting the nucleus.

Atoms of different elements have different characteristics because of different amounts of protons, neutrons, and electrons.

same amount of protons and electrons, neutrally charged

different numbers of electrons than original

type of ion where atom has more protons than electrons, positively charged

type of ion where atom has more electrons than protons, negatively charged

different number of neutrons

hold atoms together within a molecule

bond that exists between molecules

intramolecular

a group of 2+ atoms held together by chemical bonds (H2, O2, and O3)

different types of atoms chemically bonded (CaCl2 or NaBr)

formed when non metal atoms share their valence electrons to gain octets (a full valence shell)

one atom gives up electron to another atom

two water molecules bonding because of the positive ends of hydrogen molecules bonds with the negative end of the oxygen molecules

covalent

Positively charged subatomic particle

negatively charged subatomic particle

neutrally charged subatomic particle

Center/core of an atom, consisting of protons and neutrons

Regions surrounding the nucleus containing a specific number of electrons

The smallest particle of matter that contains the characteristics of an element

The number of protons in an atom

The total number of protons and neutrons in an atom

Unrounded number of the mass of an atom

Electrons in the outer shell of an atom

atoms being positively and negatively charged

Molecules of the same substance bonding

Molecules of different substances bonding

The ability water has to flow upward against the force of gravity due to cohesion and adhesion.

Universal Solvent - liquid that dissolves most/all solutes (water)

a liquid that dissolves a particle

particle or liquid that gets dissolved in the solvent
