Q

What was Mendeleev’s Proposal regarding the arrangement of elements within the periodic table?

A

Elements are arranged in rows based on increasing mass, and elements with similar properties are within the same column

Q

How did Mendeleev Predict properties of unknown elements?

A

He left empty spaces in the table and used properties of nearby elements to predict the future ones

Q

What evidence suggests that Mendeleev’s model was a good one?

A

Later it was found that there’s a very close match between Mendeleev’s predictions and the actual properties of new elements

Q

what properties do nonmetals have?

Study These Flashcards
A

opposite of metals

25
what are transition metals?
bridges between elements on the left and right side of the table
26
describe metalloids
stair-step pattern, conductibility varies w/ temp. better than nonmetals but not metals
27
variation across periods (l to r)
atomic size decrease, metallic properties decrease, ability to gain electrons increase EXCEPT NOBLE GASES
28
what are valence electrons? (VA)
outermost electrons
29
how many electrons can fit on each energy level?
2, 8, 18, 32
30
What particle is responsible for chemical properties of an element?
Valence Electrons
31
what do metals do to get full outer energy level (8 VE)?
lose electrons
32
what do non-metals do to get full outer energy level (8 VE)?
gain electrons
33
what do some nonmetals and metalloids do to get full outer energy level (8 VE)?
share electrons
34
oxygen has 8 protons. how many valence electrons does it have and why?
6 because 2 electrons go on the inner level, leaving six left to go on the outer level
35
What are the eight major groups on the periodic table in order?
Alkali metals, Alkaline Earth Metals, Boron Group, Carbon Group, Nitrogen Group, Oxygen Group, Halogens, and Noble Gases
36
Four properties of alkali metals (group 1)
- 1 VE - Soft, shiny, silver/white metals - Never found pure - Most reactive metals
37
four properties of Alkaline earth metals (group 2)
- 2 VE - Not as reactive as alkali metals - often mixed with aluminum - forms strong/light weight alloys
38
What is magnesium used for?
making steel
39
what is calcium found in?
chalk, limestone, pearls, plaster
40
Four properties of the Boron Family (group 3)
- 3 VE - Hard/brittle - never found pure in nature - in borax, cosmetics
41
what metal is most abundant in earth's crust?
alumonum
42
What element is the second most abundant in Earth's crust?
Silicon
43
Three properties of Carbon family (group 4)
- 4 VE - Can gain/lose/share 4 ve - most compounds in body contain C
44
Three properties of Nitrogen family (group 5)
- 5 VE - Tend to gain 3 VE - P on the tips of matches
45
Four properties of the oxygen family (group 6)
- 6 VE - tend to gain 2 VE - O is very abundant - O is needed for digestion
46
What three elements are commonly used in fertilizers?
N, P, and S
47
What is another term used for the halogen family?
salt-former
48
Four properties of Halogen Family (group 7)
- 7 VE - Most reactive nonmetals - Never found pure in nature - Reacts w/ alkali metals well
49
what do halogen and alkali metals form when reacting with eachother?
salts
50
what is the most reactive halogen?
F
51
What is F used in?
Compounds in toothpaste
52
Which element efficiently kills bacteria?
CI
53
Four properties of the Noble Gases (group 8)
- 8 VE - non-reactive - "neon' lights - less than 1% of earth's atmosphere
54
What single element doesn't have eight VE in the Noble Gases?
Helium
55
Four properties of transition metals
- solids at room temperature - ductile, malleable, conductors - VE varies - less reactive than groups one and two
56
What is the exception of all transition metals being solids at room temperature?
Hg
57
What three transition metals form a magnetic field?
Fe, Co, and Ni
58
What are the two series of rare earth elements?
Lanthanide and Actinide Series
59
Three properties of the rare earth elements
some radioactive, silver/white/gray metals, conduct electricity
