HELP ME WITH MY CHEMISTRY i'm over loaded with things to do?
today is my dad's birthday and i have sooo many things to do it's horrible i got to take care of my lil sister and brothers then bake his cake
pleas help
1)Which trend decreases for metals down a group?
2)Which trend decreases as you move up a group and across a period from left to right?
3)Which of the following is the least reactive? ( calcium, strontium, radium, magnesium. barium)
4) Electronegativity ___________ as you go down a group.
5)Potassium is a(n) ( metal non metal alkali metal?)
6)onization energy increases as you go down a group.( true false)
7)Which of the elements listed is the least reactive?( sodium, alimunm,lithium magnesium)
8)Elements in the same group of the periodic table have the same
9)Ununquadium is in period:
Answer:
Dude i have been through the same thing and it just makes my day worse oh well..
1) Electronegativity
2) Well several of factors but i will have to say the key one is the atomic radius and it decreases as you go from left to right because of the increase in the atomic number.
3) It has to be magnesium because the trend is that the reactivity of the metals increases as you go down the group.
4) Decreases regardless of what group it is.
5) It is an alkali metal because it will make the solution more alkaline i.e. pH above 7 if dissolved in water.
6) It will decrease because the outer electrons will be further away from the strong positive nucleus so therefore false.
7) Aluminium as it has a high charge density.
8) Chemical properties because they will have the same number of electrons in their outer shell.
9) It took me long to search for it.. it is in period 7
hope it helps :)
1) Electronegativity tends to decrease as you move down a group.
2) Atomic radius tends to decrease as you move up a group and across a period from left to right.
3) In order from least to most reactive: Mg<Ca<Sr<Ba<Ra
4) Electronegativity decreases as you move down a group.
5) Potassium is an alkali metal.
6) Ionization energy decreases as you move down a group. False.
7) Al is the least reactive.
8) Don't know what you are asking for...same what?
9) Ununquadium is in period 7
