BELL WORK: TUESDAY 11/16/10

•Which group of elements in the Periodic Table is least reactive?

•Why?Noble gases, inert gases, Group 8a, Group 18

Their valence electrons are in complete orbitals ns2np6

Guided Notes: Cations and AnionsFirst, some basics:• A neutral atom that gains one or more

electrons will have a ________________ charge.

• A neutral atom that loses one or more electrons will have a ________________ charge.

• An atom that has a charge is called an ___________.

• A positive ion is called a _______________.

• A negative ion is called an ____________.

negative

positive

ion

cation

anion

Why would an atom lose one or more of its electrons?

Why would an atom gain one or more electrons?

Let’s build some atoms and ions and see if we can find out.

1. Metals in group __ lose one electron to obtain a ____ ____ _______________. They become Li+, Na+, K+ etc.noble gas configuration

2. Metals in group ___ lose ____ electrons to obtain a noble gas configuration. They become Be2+, Mg2+,

Ca2+ etc.

3. Halogens in group ___ gain ___ electron to obtain a noble gas configuration. They become F-, Cl-, Br- etc.4. Elements in group ___ gain ___ electrons to obtain a noble gas configuration. They become O2-, S2-, Se2- etc.
