Select two different groups from the periodic table & describe all the characteristics that make the elements in the group similar. Create a fictitious element. Does it fit in one of the two groups you selected? Why or why not?

Question

joannablackwelder · Answer

What two groups would you like to use?

anonymous · Answer

thanks so much for the help!!! and halogens - group 17 and noble gases - group 18

joannablackwelder · Answer

Ok. No worries :) Can you list the characteristics for the halogens?

anonymous · Answer

I actually have no idea :( that's what I need help with
 :/

joannablackwelder · Answer

Oh, ok. Here is a pretty goo list. http://www.ehow.com/list_6795201_halogen-family-characteristics.html

haha

anonymous · Answer

I found this 
Group 18, better known as the noble gases, are a group of elements that have a full outer shell and will therefore not have a tendency to react. Elements in this group are inert and gaseous, which is why they're called the noble gases.

Group 17, called the halogens, are a peculiar class of nonmetals. All halogens have 7 valence elections, making them EXTREMELY reactive (especially with Group 1 and 2). Halogens have high electronegativities and vary in physical properties 

but idk how to put it in my own words and how to explain it

joannablackwelder · Answer

Give it a shot and I will help you correct anything you may have misinterpreted. :)

joannablackwelder · Answer

Read through it a few times to get the idea, then try to write it without looking at it.

anonymous · Answer

noble gases also known as group 18, is a group of elements that do not react because their outer shell is full. the elements that are in group 18 have the characterists of inert and gaseous, and that is why they are the noble gases.

Halogens also known as group 17, is a different type of nonmetals elements. every  halogen has 7 valence elections, which makes them EXTREMELY active, and extremely reactive with groups 1+2. Halogens have high electronegativities and vary in physical properties

anonymous · Answer

is that good?

joannablackwelder · Answer

Wow, that is almost too good. It is REALLY close to the copied paragraphs.

anonymous · Answer

I tried to have the same concept but I changed most of the words. except the last sentence

anonymous · Answer

and what about the last part -  Create a fictitious element. Does it fit in one of the two groups you selected? Why or why not?

joannablackwelder · Answer

How about something like this:
Group 18 elements are generally nonreactive (inert) and gaseous, thus they are called the noble gases.The reason that they are nonreactive is that they already have a full valence electron octet.
That keeps the idea, but changes it up a little bit more.

joannablackwelder · Answer

Creating a new element is to basically come up with the characteristics of the element. If it is similar in characteristics to either group 17 or 18 then it would fit in one of those groups. If not, then it would not. :)
