What is the group name of column 1 on the periodic table?

The group name of column 1 is alkali metals. They are metallic and basic in nature.


Where is alkali metals located on the periodic table and their group number?

Alkali metals are located in Group 1 of the periodic table, which is the first column on the far left. They include elements like lithium, sodium, and potassium.


What elements are found in Group 1A sometimes referred to as Group 1?

Potassium and Hydrogen


How many valence electrons does a group 1A metal atom have?

A group 1A metal atom has 1 valence electron.


What is the group that hydrogen is in?

Hydrogen is in group 1 of the periodic table, also known as the alkali metals group.


What are the most active metals in group 1A increases?

The reactivity of the alkali metals increases as you go down column 1 (or 1A) in a periodic table. This occurs because the first ionization energy of the metals decreases, as a result of "shielding" the outermost electrons from the attraction of the positive nucleus by the inner electrons.


What family or column is lithium found in the periodic table?

Lithium is found in the alkali metals family, specifically in the first column of the periodic table.


How is the ionic charge of a group 1A 2A or 3A ion determined?

The ionic charge of a group 1A, 2A, or 3A ion is determined by the number of electrons lost or gained to achieve a full valence shell. Group 1A ions lose 1 electron to attain a +1 charge, group 2A ions lose 2 electrons for a +2 charge, and group 3A ions lose 3 electrons for a +3 charge.


What do atoms in group 1A have?

Atoms in Group 1A (also known as Group 1 or alkali metals) typically have one electron in their outermost shell. This gives them a tendency to form +1 cations by losing this electron to achieve a stable electron configuration. Group 1A elements include lithium (Li), sodium (Na), potassium (K), and others.


What is 1 to the power of 2 plus 1a-1a plus 1?

12 + 1a - 1a + 1 = 1 + 0 + 1 = 2


Mendeleev's name for a column of elements?

Mendeleev named each column of elements in his periodic table a "group." These groups were arranged according to similar chemical properties and were numbered from 1 to 8.


What is the number of valence electron for all the elements in periodic table group 1A 1?

Group 1A (1) elements in the periodic table all have 1 valence electron. This includes elements like hydrogen, lithium, sodium, and potassium.
