is group 8 reactive or unreative

Answer 8

unreactive becuase it is very difficult for them to lose or gain electrons becuase of full outer shell

soft light gray and shiny when cut with knife

Question 20

what is the density of group one metals

Answer 20

low

Question 21

what do group one metals reactive with

Answer 21

a basic solution and hydrogen gas

Question 22

what happens to the melting and boiling points of group one as you go down

Answer 22

they decrease

Question 23

what happens to the reactivity of group one as you go down

Answer 23

it increases becuase its easier for the outer shell to lose its electron due to how far away it is away from the nucleus

Question 24

what happens to reactivity in group seven as you go down

Answer 24

they decrease becuase its harder for the atoms to gain the electrons they need becuase of the weaker electrostatic charges caused by distance

Question 25

what do group seven naturally exist as

Answer 25

diatonic

Question 26

what happens to melting and boiling points in group seven as you go down

Answer 26

they increase

Question 27

what happens to density of group one metals as you go down

3- or 3+

Question 43

are ionic compounds soluble in water

Answer 43

often

Question 44

why are ionic compounds soluble in water?

Answer 44

water is attracted to charged ions and therefore many of the ionic solids dissolve

Question 45
