| 1 |
Elements within each group of the periodictable behave similarly because...
|
they havethe same number of valence electrons
|
|
| 2 |
What are valence electrions?
|
the electrons in thehighest occupied energy level of anelements atoms.
|
|
| 3 |
What do Valence electrons determine?
|
Valence electrons determine the chemicalproperties of an element.
|
|
| 4 |
How do you find the numberof valenceelectrons in anatom of arepresentativeelement
|
Look at the element's group number.
|
|
| 5 |
OctetRule
|
In forming compounds, atoms tend togain or lose electrons in order toachieve the electron configuration...
|
|
| 6 |
Atoms of metalslose their...
|
Valence electrons
|
|
| 7 |
Atoms of somenonmetals tend to..
|
gain electrons or toshare with othernonmetallicelements to achievea complete octet
|
|
| 8 |
When an atom loses an electron
|
itproduces a positively charged ion, or acation.
|
|
| 9 |
The most common cations
|
are thoseproduced by the loss of valence electronsfrom metal atoms.
|
|
| 10 |
The gain of negativelycharged electrons bya neutral atom
|
produces an anion.
|
|
| 11 |
valence shell
|
outermost shell of electrons of an atom.
|
|
| 12 |
Compounds composed ofcations and anions arecalled
|
ionic compounds
|
|

The electrostatic forces that hold ionsTogether in ionic compounds are
