Document Summary
Read labs before doing them (for quizzes) In science we assume that our observations give us useful information about the. We propose natural explanations for natural phenomena. We test proposed explanations using observations of the universe to see if it makes. Such a test requires that we can identify observations that would be inconsistent and not. Fact- a hypothesis confirmed to such a degree that it would be perverse to withhold. Atom- the smallest unit of an element that retains all of that element"s properties ( if you. Isotopes - atoms with the same number of protons that are the same element but they. Valence shell- the outermost shell that contains one or more electrons. Covalent bond (a chemical bond in which fill their valence shells, when they share they both have a full valence shell. the electrons hold the atoms together- this is a two atoms share one pair of valence electrons)
