Li Na K Rb Cs Fr (hope this is help)
Yes.
alkai metals, alkaline earth metals, lanthanoids, actinoids, transistion metals, poor metals, other non-metals, noble gases.
Lithium belongs to Group 1 and Period 2 of the periodic table.
the s-block elements are highly reactive elements, on the other hand, d-block elements are less reactive than the alkai metals and the alkai-earth metals. some are so reactive that they do not easily form compounds.
Atomic emission spectrometry is limited to alkali metals.
Their symbol, atomic weight, and atomic number.
Atomic symbols are considered nouns because they are used to represent specific elements in the periodic table.
weird weird
The full atomic symbols for uranium are: Uranium-235: ^235U Uranium-238: ^238U
Elements to the left of the periodic table are called metals. These elements generally have low ionization energies and tend to lose electrons to form cations. They are good conductors of heat and electricity.
The chemical reactivity of alkali metals increase when the atomic number increase.
