<p>groups 1 &amp; 2</p>

groups 1 & 2

what groups are the s-block elements?

New cards
10
<p>alkali metals</p>

alkali metals

silvery appearance

soft enough to cut with knife

very reactive, must be stored in kerosene bc they will react with the water in the air

not found in nature as free elements, only in compounds

group 1

New cards
11
<p>alkaline earth-metals</p>

alkaline earth-metals

harder, denser, & stronger than alkali metals

higher boiling point

less reactive but also not found in nature as a free element

group 2

New cards
12
<p>H &amp; He</p>

H & He

unique, does not share the same properties of group 1

New cards
13
<p>groups 3-12</p>

groups 3-12

what groups are the d-block elements?

New cards
14
<p>transition metals</p>

transition metals

good conductors, high luster

typically less reactive than alkali and alkaline-earth metals

some so nonreactive they do not easily form compounds & exist as free elements

groups 3-12

New cards
15
<p>gold, palladium, platinum</p>

gold, palladium, platinum

What are the least reactive transition metals?

New cards
16
<p>groups 13-18</p>

groups 13-18

what groups are the p-block elements?

New cards
17
<p>main group elements</p>

main group elements

made up by the s-block and p-block elements

properties vary greatly

New cards
18
<p>nonmetals</p>

nonmetals

What kind of metals does the right side of the p-block have?

New cards
19
<p>metals</p>

metals

What kind of metals does the left side and bottom of the p-block have?

New cards
20
<p>metalloids</p><p>boron, silicon, germanium, arsenic, antimony, tellurium</p>

metalloids

boron, silicon, germanium, arsenic, antimony, tellurium

What kind of 6 metals in the middle of the p-block called? What are they?

New cards
21
<p>halogens</p>

halogens

What is group 17 called?

New cards
22
<p>halogens</p>

halogens

most reactive metals

react very vigorously with most metals to form salts

New cards
23
<p>metalloids</p>

metalloids

semiconducting elements

located in the p-block between metals and nonmetals

brittle solids w/ properties of both metals and nonmetals

New cards
24
<p>metals of the p-block</p>

metals of the p-block

harder and denser than the s-block metals, but softer than the d-block metals

New cards
25
<p>lanthanides and actinides</p>

lanthanides and actinides

What does the f-block consist of?

New cards
26
<p>lanthanides</p>

lanthanides

shiny and similar to group 2 reactivity

New cards
27
<p>actinides</p>

actinides

radioactive and only 1st four found naturally on earth, the rest made in the lab
