Li is an element. It is in the 1st group. It is an alkaline metal element.
Potassium (K) is more similar to lithium (Li) than to lead (Pb) because both K and Li are alkali metals located in the same group (Group 1) of the periodic table. They share similar chemical properties, such as reactivity and the formation of +1 ions. In contrast, lead (Pb) is a heavier post-transition metal in Group 14, exhibiting different properties and behaviors. Thus, K's similarities in group characteristics align it more closely with Li.
Na (sodium) closely resembles lithium (Li) as both elements belong to the same group on the periodic table and share similar chemical properties such as reactivity and the ability to form compounds with other elements.
Francium is the least reactive metal in the alkali metal group. This is due to its large atomic size and low electronegativity, which result in weaker attraction to electrons and less reactivity compared to other alkali metals. However, francium is extremely rare and radioactive, making it difficult to study its chemical properties.
LiOH is a strong base
No, lithium (Li) and fluorine (F) are not very similar. Lithium is a metal, while fluorine is a nonmetal. They have different chemical properties, with lithium being an alkali metal and fluorine being a halogen.
Any element in the alkali metal group would have similar chemical properties, for example they all react easily to water.
Lithium is a "soft, silver-white metal that belongs to the alkali metal group of chemical elements." Its chemical symbol is 'Li'
Metal
No, Li (lithium) is a metal.
Potassium's siblings on the periodic table are sodium (Na) and lithium (Li). These elements are all found in the same group, Group 1, and share similar chemical properties such as being highly reactive with water.
I think you lost some formatting there. Na+ is isoelectronic with neon, if that's what you were trying to ask.
