Group 1 elements, also known as alkali metals, are typically shiny and have a silvery appearance when freshly cut. They are soft and can be easily shaped, with lithium, sodium, and potassium being particularly notable for their metallic luster. However, due to their high reactivity, they quickly tarnish in air, forming a dull oxide layer. These elements are characterized by low melting and boiling points compared to most metals.
Group 1 Metals
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
Group 1 elements are more reactive than that of group 2 elements.

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.
Group IA or group 1 elements are known as alkali metals.
Group 1 elements are more reactive than that of group 2 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 a.k.a. Alkali metals lose 1 electron to form 1+ ions
Group 1 elements are metallic in nature. They have 1 electron in their outermost octet.
