Group Properties of Elements G-IA Flashcards
Do not occur free in nature
GROUP 1A: ALKALI METALS
V ery active chemically; displace all other elements from
their chemical compound
GROUP 1A: ALKALI METALS
Oxides & hydroxides are strongly basic
GROUP 1A: ALKALI METALS
Alkali halides are soluble in water & are not hydrolyzed
GROUP 1A: ALKALI METALS
Univalent; V alence = +1
GROUP 1A: ALKALI METALS
Form simple cation; do not form complex cation with
ammonia
GROUP 1A: ALKALI METALS
All rapidly oxidized in air
GROUP 1A: ALKALI METALS
Water forming - when burned with O2
HYDROGEN (H2)
Inflammable air
HYDROGEN (H2)
Lightest element; Element common to all acids
HYDROGEN (H2)
Preparation: Lane & Messerschmidt process (99% pure
H2- conversion of water to H2 )
HYDROGEN (H2)
Three Isotopes: (same proton/ atomic number, di erent
atomic mass)
1. Protium- most abundant
2. Deuterium- heavy hydrogen (D2O: Heavy
water/ deuterated water, solvent for NMR)
3. T ritium- radioactive
HYDROGEN (H2)
Industrial uses:
○ Haber process
HYDROGEN (H2)
Industrial uses:
Gas Chromatography gas carrier/ mobile
phases (also: Helium,
- most common mobile
phase in GC; Nitrogen)
HYDROGEN (H2)
Industrial uses:
Balloon inflation
HYDROGEN (H2)
Industrial uses:
Oil hydrogenation - margarine production
HYDROGEN (H2)
Lithos (earth, rock)
LITHIUM (Li)
Lightest metal
LITHIUM (Li)
Depressant & Diuretic
(S/E: hypovolemia, hyponatremia)
LITHIUM (Li)
Mood stabilizer (sedative); DOC for
manic/bipolar disorder
(S/E: narrow Therapeutic index)
LITHIUM (Li)
