Homework Help: Science-Periodic Table

Posted by Sara on Thursday, April 8, 2010 at 7:36pm.

Where r the elements that form ions with a positive charge located?

where r the elements that form ions with a negative charge located?

can someone please briefly explain this whole positive and negative charge thing to me. I kind of get it, but the informations is just not clarified in my head. I think that the elements which form ions with a negative charge are located in the nonmetals column?

Where are the non-metals?

They are on the right upperside of the periodic table.

Where are the metalloids?

They are along the step like line between metals and nonmetals of the periodic table.

I am also having troubles with this Q.

what shap does the layout of the metalloids form in periodic table?

All ur help will be greatly appreciated, thanks

right on location of metals, nonmetals.
metalloids form a stairstep down to right starting at boron.

Metal ions form + ions by losing electrons.

Non metal ions form - ions by gaining electrons.
