Group one elements have one valence electron. In order to achieve a "happy" electron configuration, they try to lose this valence electron. Electrons have a negative charge, so once they lose this electron, they have a +1 charge.
The effective nuclear charge decreases as you move down a group in the periodic table because the number of electron shells increases, leading to greater shielding of the outer electrons from the positive charge of the nucleus.
Electronegativity generally increases as you move from left to right from group 1 to group 17 on the periodic table. The noble gases in group 18 generally don't have an electronegativity since they generally don't make compounds.
As you move down a group in the periodic table, the effective nuclear charge generally decreases. This is because the number of energy levels or shells increases, leading to more shielding of the outer electrons from the positive charge of the nucleus.
Elements in Group 13 of the periodic table, also known as the Boron group, can form cations with a 3+ charge. This is because they can lose three electrons to achieve a stable electronic configuration. Key elements in this group include Boron, Aluminum, Gallium, and Indium.

Elements in group one of the periodic table; Lithium, Sodium, potassium, rubidium, caesium and rubidium, will form ions with a positive charge of one.

The trend of effective nuclear charge down a group in the periodic table generally decreases.
The halogens, listed in column 17 of a wide form periodic table.
Hydrogen is placed in group I of the periodic table because it has one valence electron, similar to the other elements in this group, such as lithium, sodium, and potassium. Additionally, hydrogen shares some chemical properties with the elements in group I, specifically in terms of forming positive ions (cations) with a +1 charge.
The periodic table has a regular repeating pattern based on the arrangement of elements by increasing atomic number. Elements in the same group have similar chemical properties due to their shared number of valence electrons. This pattern helps predict the chemical behavior of elements.
Group 3 and lanthanides.
Elements from the group 2 of the periodic table form cations.
