3)
1 calorie = ____ joules - ANS-four.184 J
1 g= ? Mg - ANS-a thousand mg
1 inch = ? Cm - ANS-2.54 cm
1 kg= ? G - ANS-a thousand g
1 L = ? ML - ANS-one thousand mL
one thousand Joules= ____ kilojoule - ANS-1 kJ
three components of the nuclear principle of the atom - ANS-1) Most of the atom's mass and all
of its tremendous price are contained in a small core referred to as a nucleus
2) Due to electrons being spaced out in the cloud, maximum of the volume of an atom is simply
empty area
3) There are as many negatively charged electrons out of doors the nucleus as there are
undoubtedly charged particles inside the nucleus, making the atom electrically impartial
A combination... - ANS-is a blend of two or more styles of count number, each of which retains
its own identity and residences
A natural substance... - ANS-has a set composition
alkali metals - ANS-Group 1
alkaline earth metals - ANS-Group 2
Anion - ANS-A negatively charged ion
Atom - ANS-Smallest particle of an element
atomic mass - ANS-Number of protons and neutrons
atomic quantity - ANS-variety of protons
common atomic mass - ANS-mx= a1m1 + a2m2 +a3m3.....
, Avogadro's range - ANS-6.02 x 10^23 gadgets/ 1 mol
c=vλ - ANS-C=Speed of mild (3.00x10^8 m/s)
v= frequency (hz or S^-1)
λ= wavelength (devices)
Cation - ANS-A undoubtedly charged ion
Centi- - ANS-10^2 c unit= 1 unit
Chalogens - ANS-Group sixteen
optimistic interference - ANS-waves combine to make a wave with a larger amplitude
Deci- - ANS-10^1 D unit = 1 unit
Density - ANS-mass/volume
detrimental interference - ANS-waves cancel every different out
Diffraction - ANS-Occurs when an item reasons a wave to alternate route and bend around it
(results in an interference sample)
Dr. Forbe's rule for sig figs: - ANS-locate the first non zero number and be counted till the quit of
that quantity
E= hc/λ - ANS-c=λv AND E=hv
E=hv - ANS-e= energy (J, Joules)
h=planks steady (6.6262*10^-34J)

electron affinity - ANS-the energy trade associated with adding electrons to atoms
electron affinity increases ________ and decreases _________ - ANS-across a duration; down
a group
Electronegativity - ANS-the potential of an atom to draw electrons when the atom is in a
compound
massive property - ANS-a assets that is depending on the amount of substance present
first ionization power - ANS-the strength required to eliminate the first electron from an atom
