types of elements and groups

Question 1

what category of elements are in group 1

Answer 1

Alkali Metals

Question 2

what category of elements are in group 2

Answer 2

alkaline earth metals

Question 3

what category of elements are in group 3-12

Answer 3

D-transition or transition metals

Question 4

what category of elements are in group 17

Answer 4

halogens

Question 5

what category of elements are in group 18

Answer 5

Nobel gases or inert gases

Question 6

describe noble gases

Answer 6

unreactive
have a maximum number of electrons in their outer shell
used in ad signs, toys, and blimps

Question 7

describe alkali metals

Answer 7

highly reactive
they react vigorously to lose their extra electron
good conductors of heat and electricity
soft enough to be cut with a knife

Question 8

describe alkaline earth metals

Answer 8

reacts less violently to water
has to loose two extra electrons to become a noble gas
harder than alkali but softer than many metals

Question 9

describe d-transition and transition metals

Answer 9

many are hard
excellent conductors in heat and electricity
low reactivities

Question 10

Describe halogens

Answer 10

highly reactive
combines with metals to form salt
need one more electron to become a noble gas

Question 11

describe hydrogen

Answer 11

non-metallic gas
reacts slowly at room temperature
reacts fast when heated

Question 12

what is the top row of the bottom of the periodic table

Answer 12

lanthanides

Question 13

what is the bottom row of the bottom of the periodic table of elements

Answer 13

actinides

Question 14

describe lanthanides

Answer 14

shiny, reactive metals

used in tv

Question 15

describe actinides

Answer 15

radioactive elements
