FoundationWhich property sets the order of elements in the modern periodic table?
Need a small nudge?

It is the whole number shown for every element.

UnderstandingWhy do main-group elements in the same group often show similar chemical behavior?
Need a small nudge?

Focus on their outermost electrons.

ApplicationWhat is the general trend in atomic radius from left to right across a period?
Need a small nudge?

The nuclear charge rises while electrons are added to the same principal shell.

InterpretationWhich atom is more electronegative, fluorine or chlorine, and why?
Need a small nudge?

Compare their positions within Group 17.

ConnectionAn element is in Period 3 and Group 17. Which ion is it most likely to form in a simple ionic compound?
Need a small nudge?

Identify the element, then consider how many electrons complete its valence shell.
