The Alkali Metals
The elements (not atoms) in family 1 (group I) are called alkali metals.
Group 1 Metals
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
Group 1 elements have an oxidation number of +1.
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Group IA or group 1 elements are known as alkali metals.
Group 1 elements are more reactive than that of group 2 elements.
alkali metals (group 1 elements)
Elements in group 1 (alkali metals) have 1 valence electron. This single electron is in the outermost energy level of the atom, making these elements very reactive and likely to lose this electron to achieve a stable electron configuration.
Group 1 elements are metallic in nature. They have 1 electron in their outermost octet.
Group 1 elements a.k.a. Alkali metals lose 1 electron to form 1+ ions
