QuestionAnswer
Boyles Law the volume of gas varies inversely with pressure P1V1=P2V2
Charles Law volume of a fixed mass of gas is directly proportional to its Kelvin temperature if the pressure is kept constant. V1 V2/T1 T2
Dalton’s Law total pressure of a mixture of gases is the sum of the partial pressures of all the gases is the sum of the partial pressures of al the gases present PT=P1+P2+P3+…
Gay-Lussac’s Law the pressure and Kelvin temperature of a gas are directly proportional at constant volume P1/T1=P2T2
Atomic Orbitals a region in space around the nucleus of an atom where there is a high probability of finding an electron
Columns 1A and 2A comprises the ____-block referring to electron configurations S
Columns 3A(13) through the noble gases(18) comprises the ___-block P
The inner transition metals comprise the ___-block F
The transition metals comprise the ___-block (3-12) D
Which element has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2 ?
Order of Electron configurations 1s 2s 2p 3s 3p 4s 3d 4p 4p 3s 4d 5p 6s 4f 5d 6p 7s 5f 6d 7p 6f 7d 7f
How many electrons does p, d, f, and s hold? d=10 p=6 f=14 s=2
There are __ periods and __ groups 7 periods and 18 groups
Metals are at the__, non metals__ metalloids Metals are at the left, non metals at the right and metalloids along the steps
The alkali metals belong to group 1A
the alkhali earth metals belong to group 2A
halogens belong to group 7A
rare gas such as neon group 18 8A
transation metals group 3-12A
Valence electron is the same as their group As
Na has __ valence electron 1
Cations are__ ion +
anions are __ -
metals __ electronis to form __ ions lose to form positive
Non Metals __ electrnos to form __ ions gain to form negative
Metals combine with non metals to form Ionic bonding
Na+F Na+F-
Covalent booding is formed when atoms of _share electrons non-metals
H2 H-H
The name is metallic ions(group 1-3) is the same as the name of the element followed by the word _ or_ example na+ is Ion or cation sodium ion(cation)
The name is non-metallic ions uses the stem of the element's name and ends with__ example Cl- "ide" chloride
fe3+ Iron(III) ion
Cu2+ Copper(II)
Polyatomic ions ends with __ or__ ite or ate
Binary ionic compounds contain 2 elements. Only __ and __ a metal and a nonmetal
name each NaCl Sodium Chloride
Binary molecular compounds contain 2 elements only. 2 __ nonmetals
true/flasethe names of molecular compounds contain numerical prefixes to indicate the # of each atom in the formula. ex: CO carbon monoxide true
name each N2O4 nitrogen tetroxide
steps on how to write binary ionic compound 1. write the symbol of ions2. write the symbol of ions again and reverse the # and write them at the bottom right side of the symbol ex: Na+O2- = Na2O3. write in sumplest ratio/form
Write the symbol:Pb2O4 Lead(IV) oxide
