Flashcards in Inorganic Chemistry Deck (37):
Anything that occupies space/has mass (elements, compounds, and mixtures)
Basic building blocks of all matter/smallest possible particle of an ELEMENT not life
Subatomic particle with a positive charge➕, located in nucleus, 1amu
Subatomic particle with a neutral charge, located in nucleus, 1amu
Subatomic particle with a negative charge➖, orbits around nucleus, basically no mass
Number of PROTONS (only=electrons in a non ion)
Mass of Protons+Neutrons in nucleus (round to nearest whole #)
Number of electrons in each energy level/cloud
How do you tell the number of valence electrons?
Periodic table: 1v, 2 (skip transition metals) 3, 4, 5, 6, 7, 8 (noble gas)
Two or more atoms held together by COVALENT bonds/type of compound/nonmetal+nonmetal/no salts
A group of identical atoms
Two or more different elements in a fixed ratio (covalent or ionic)
What elements make up organic matter?
Carbon (C) and Hydrogen (H) (nitrogen is also important)
Same number of protons, different number of nuetrons
TRANSFER metal (lose) and nonmetal (gain) to become a salt/crystal (becomes atoms with opposite charges that are attracted to each other and easier to break than covalent)
A metal atom that loses electrons (LEO says GER)
A nonmetal atom that gains electrons (LEO says GER)
SHARE nonmetal+nonmetal/molecules/shown with line which represents a pair of 2 electrons/harder to break than an ionic bond
The # of covalent bonds an atom can form is the..
# of valence electrons needed to fill outer shell (H can form 1, O can form 2, etc) maximum 3 bonds between 2 elements but can form bonds with other elements if it needs more
Polar covalent bond
Atoms that do not exert the same pull on shared electrons/The stronger atom ends up with a slight negative charge (more electrons on that side)
Nonpolar covent bond
No difference in charge between the two ends of bonds (diatomic N2, O2 etc)
Not chemically combine ex salt water
2 of the same element (O2, N2, H2, Cl2)
Form hydrogen ions (H+) in solution...
HCl hydrochloride acid dissolves in H+ and Cl-/less than 7 pH/Electrolyte
Electrolytes/ types of Electrolytes
Free moving ions in a mixture that conducts electricity. Aqueous salts (NaCl MaCl) and Acids (HCl HNo) and Bases (NaOH)
Breaks up, Cl- attracts to H+ and Na+ attracts to O-,
As water cools, hydrogen bonds..
Form and release energy to moderate temp
As water heats, hydrogen bonds..
Break and absorb energy to moderate temp
Measures the hydrogen ion (H+) concentratin
0(most acidic)--7(nuetral)--> 14(basic)
Hydrogen bonds form intermolecular attraction when?
(O-) is attracted to (H+) causing cohesion, adhesion, and capillary action
Any compound that produces hydroxide ions (OH-) when dissolved in water...
NaOH sodium hydroxide dissolves into Na+ and OH-/Electrolyte
