What are facts about the alkai metals?
Alkali metals are located in group 1 of the periodic table and include elements such as lithium, sodium, and potassium. They are highly reactive, especially with water, and are soft enough to be cut with a knife. Alkali metals have a single electron in their outermost shell, making them ready to lose that electron to form positive ions.
What is alkai metal?
Alkali metals are a group of highly reactive elements located in the first column of the periodic table, including lithium, sodium, potassium, rubidium, cesium, and francium. They are known for their low density, softness, and high reactivity with water. Alkali metals are used in various applications such as batteries, fireworks, and pharmaceuticals.
What is the origin of flame colors?
Flame colors are caused by the excitation of electrons in various elements present in the material being burned. Each element emits a characteristic color when heated, based on the energy levels of its electrons. This phenomenon is used in flame tests to identify elements in compounds.
How do the electron arrangement differ between the alkai metals and the nobal gases?
Alkali metals have a single electron in their outermost energy level (valence shell), which makes them highly reactive as they tend to lose that electron easily to achieve a stable electron configuration. In contrast, noble gases have full outer electron shells, meaning their valence levels are completely filled with electrons, making them stable and mostly unreactive. This fundamental difference in electron arrangement is the reason behind the contrasting chemical properties of these two groups in the periodic table.
Why are all alkai metals highly reactive?
well basically they all have very unstable atoms and having unstable atoms. They also have only 1 outer electron and only then is an atom happy when it has a full outer shell.. This means that the alkali metals want to get rid of their extra electron and therefore means they would be very reactive with the group 7 metals. Hope this helps :D
What are elements to the left called?
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.
Difference between s-block metals and d-block metals?
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.
What is the Group name or number of lithium?
Lithium belongs to Group 1 and Period 2 of the periodic table.
What are the 8 most common elements on the Earth?
alkai metals, alkaline earth metals, lanthanoids, actinoids, transistion metals, poor metals, other non-metals, noble gases.

What are the atomic symbols for alkai metals?
Li Na K Rb Cs Fr (hope this is help)
How many family members does the element mercury have?
Mercury is a member of Group 12 on the periodic table, also known as the zinc group. Elements in this group typically have two valence electrons. Therefore, mercury has 2 family members: zinc and cadmium, which share similar chemical properties due to their electron configurations.

Soapbleach and. alkai?
weird weird
What is it called when an acid and an alkai react?
No it is called neutralization
