thanks a lot, was really helpful!

[abundantlyrich]

Google it. 😆

[Asker]

yeah I did but they would give me the differences only

[abundantlyrich]

You are not reading it properly.

I found out from reading the properties of halogens and akali metals.

1. They are highly reactive and need to be contained in specific conditions to prevent high reactivity.

[abundantlyrich]

2. Could be they both have hydrogen atoms in their chemical properties. I really expect u younger ones to distinguish it better than I do. !

THANK YOU SO MUCH!! im sorry if i have bothered you in anyway but i was asked for 7 and I got only two and i couldn't find more so i came here to ask.

Read the chemical and physical properties for halogen and akali metals in wiki pedia links.

I went to yahoo and find it.

Anonymous male gave u a good link.

The common thing in both alkali metals and halogens is the chemistry of loosing and gaining the electrons. Since the alkali metals and halogens comes under 1st group and 17th group, they have one electron and seven electrons in the outermost shell. Alkali metals lose an electron to gain valency +1 and halogens gain an electron to attain -1 valence. In this way, both posses same valence number but one looses and one gains. Hence this is also the major reason for the attraction of these elements.

Examples for the reaction of Alkali metals with Halogens

•Lithium + fluorine →\rightarrow lithium fluoride.

2Li (s) + F2(g) 2LiF (s)

•Lithium + chlorine →\rightarrow lithium chloride.

2Li (s) + Cl2(g) 2LiCl (s)

•Lithium + bromine →\rightarrow lithium bromide.

2Li (s) + Br2(l) 2LiBr (s)

•Lithium + iodine →\rightarrow lithium iodide.

2Li (s) + I2(s) 2LiI (s)

yeah!! i have checked them out, thank you so much!!

It's... DO YOUR OWN FUCKING HOMEWORK.

[Asker]

I've done most of my homework and this is the only thing that's left, my brain can't function anymore might as well you take it easy :)

[Sam19XX]

Chemical or physical similarities? Or both?

[Asker]

both

[Sam19XX]

1-Density increases down the groups.
Dammit that is the only similarity that i know they have.
But i know so many differences between them

[Asker]

ahaha thanks a lot though!! and yeah they've got lots of differences!

[Sam19XX]

Yeah... by the way next time when you have questions like this , ask them on yahoo answers not here. There are some really educated people there ! Some of the users are university professors and they answer questions related to science whether they were easy or not.

[Asker]

will do! thank you
