The alkali metal found at the top of a group is lithium. It belongs to Group 1 of the Periodic Table and has the atomic number 3. It is the lightest and least dense solid element.
What else can I help you with?
What group 1 element is not an alkali metal?
The alkali metals are the metals in Group 1 (the first column of the periodic table). Hydrogen is also in Group 1, and so is technically considered to be part of the alkali metal group/family. Hydrogen is in fact a non-metal, however, and does not generally exhibit behavior similar to the other Group 1 elements.
What is the first of all alkali metal?
The first alkali metal is lithium, which is represented by the symbol Li in the periodic table. It is a soft, silvery-white metal that is highly reactive and commonly used in various industrial applications.
What atom has the larger atomic radius F or Fr?
Fr (Francium) has a larger atomic radius than F (Fluorine) because atomic radius increases as you move down a group in the periodic table. Francium is located at the bottom of the alkali metal group while Fluorine is at the top of the halogen group.
Is hydrogen a alkali metal or alkaline metal?
Alkali metals can be substituted for hydrogen. Any of them. They include lithim (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr). The alkali metals are in group one of the periodic table of the elements, and are all stacked up in the column below hydrogen. All the alkali metals are all organized with a lone electron in their outer most shell, or valence shell (in the neutral atom) and all of the alkali metals would like to loan out that electron to anything that would like to borrow it. It turns out that the reactivity of alkali metals are least to greatest from the top of the column to the bottom. This is because of electron screening.

What element at the top of the group?
The element at the top of a group in the periodic table is typically the lightest and often the most reactive within that group. For example, in Group 1, hydrogen is at the top, while lithium is the first alkali metal. The properties of these elements can vary significantly from those lower in the group due to differences in atomic size and shielding effects. Generally, elements at the top tend to have higher electronegativities and ionization energies compared to their heavier counterparts.
What is the element on top of the carbon group?
carbon alkali metal?
What is the relationship between an alkali metal and location in group 1A and its reactivity?
Th reactivity of alkali metals increases from the top of Group 1A to the bottom

What unusual non metal is found at the top of the same group as silicon?
Germanium is an unusual non-metal element found at the top of the group in the periodic table that also includes silicon. Germanium shares similar properties with silicon and is commonly used in semiconductors and electronic devices.
Where is the most active metal located on the periodic table Where is the most active nonmetal located?
The most active metal is francium (Fr). It is located farthest to the left and at the bottom. The most active nonmetal is fluorine (F). It is located at the top of Group 17 (the halogens).
What are elements in the tall Colomns of the periodic table called?
The generic term for columns in a periodic table is "groups". Many of the groups have specific names, but you'd have to be more descriptive than "tall" for me to be more specific.The two tallest columns on most tables are the ones the alkali metals are in and the one the noble gases are in. Hydrogen is at the top of the alkali metal group, though hydrogen itself is not considered an alkali metal. Helium is at the top of the noble gas group, and helium IS a noble gas.More notes: The column next to the alkali metals with beryllium at the top is the alkaline earth group. The column next to the noble gases starting with fluorine is called the halogens. The column starting with oxygen is the chalcogens, though that term is not nearly as widely used or recognized as the other groups that have been mentioned already. The names for the other groups are so obscure, even among chemists, that you're better off just calling them the element-at-the-top group (for example, "nitrogen group") unless you're deliberately trying to confuse people.
How do you use the periodic table to recall the ionic charge of an alkali metal or aluminum?
Look at the group number (the number along the top). Those in group I (Na, K, Li, etc) are 1+. Those in group II (Mg, Ca, etc) are 2+. Those in group III (Al, e.g.) are 3+.
Hydrogen is placed at the top of what column of elements?
It occurs at the top of the metals (alkaline metals) - the first group of elements but while normally shown at the top of the Group 1 elements in the periodic table, the term "alkaline metal" refers only to Group 1 elements from lithium onwards. (Lithium is the next one down)
Where is lithium located on the periodic table?
it is. it needs to lose 1 electron to be stable
