Electron s: ELECTRONS AVAILABLE FOR BONDING Definition Valence electrons are electrons in the outmost shell (energy
level). They are the electrons available for bonding. Group Group 11 (alkali (alkali metals) metals) have have 11 valence valence electron
electron Group Group 22 (alkaline (alkaline earth earth metals) metals) have have 22 valence valence electrons
electrons Group Group 13 13 elements elements have have 33 valence valence electrons electrons
Group Group 14 14 elements elements have have 44 valence valence electrons electrons
Group Group 15 15 elements elements have have 55 valence valence electrons electrons Group
Group 16 16 elements elements have have 66 valence valence electrons electrons Group Group 17
17 (halogens) (halogens) have have 77 valence valence electrons electrons Group Group 18 18 (Noble
(Noble gases) gases) have have 88 valence valence electrons, electrons, except except helium, helium, which which has
has only only 22 Transition Transition metals metals (d (d block) block) have have 11 or
or 22 valence valence electrons electrons Lanthanides Lanthanides and and actinides actinides (f (f block)
block) have have 11 or or 22 valence valence electrons electrons Dot Notations An atoms valence electrons can be represented by Lewis dot notations.

found in the: A. upper right-hand corner of the periodic table B. upper left-hand corner of the periodic table C. lower left-hand corner of the periodic table D. lower right-hand corner of the periodic table Poll Anywhere Cations have a ______________ charge and are ______________ than the atoms from which they formed.
A. negative/smaller B. positive/larger C. positive/smaller D. negative/larger Poll Anywhere A vertical column of elements on the periodic table can also be referred to as A. Family B. Group
C. period D. series Poll Anywhere Generally speaking the group of elements with the highest first ionization energy is A. Group 17 B. Group 1 C. Group 16 D. Group 18
