The Trends in Group IIIA Elements: Atomic size increases down the group due to the addition of new energy levels, leading to greater shielding. Ionization energy decreases down the group because of increased atomic size and better shielding of outer electrons. Metallic character increases down the group as atoms become larger and outer electrons are further from the nucleus. Each member of Group IIIA can exhibit different chemical properties and reactivity due to changes in atomic size, ionization energy, and metallic character. This lack of consistent trends makes the group irregular.
The element with the highest ionization energy in Group 3A (Group 13) is usually thallium (Tl), followed by indium (In) and then gallium (Ga). Thallium has the highest ionization energy due to its partially filled d-orbital, which imparts extra stability.
base in my experience.... because of the gravity of the earth...
Group 13 of the periodic table is known as the Boron group. It includes elements such as Boron (B), Aluminum (Al), Gallium (Ga), Indium (In), and Thallium (Tl). These elements share similar chemical properties.
Gallium has more in common with indium. Both gallium and indium are part of the same group on the periodic table, Group 13 (or Group IIIA), so they share similar chemical properties and trends. Germanium, on the other hand, is in Group 14 and therefore differs in its properties from gallium.
Boron has the largest ionization energy among the group IIIA (13) elements.

Either IA (Hydrogen) or IIIA (Boron)
The oxide formula of an element in Group IIIA of the periodic table would typically be M2O3, where M represents the element from this group. This is because elements in Group IIIA generally form 3+ cations, which combine with 2- oxide ions to form a neutral compound.
Aluminium is located in the Group IIIA - the Boron family on the periodic table.
The elements in group IIIA of the periodic table are called the boron group. This group includes the elements boron, aluminum, gallium, indium, and thallium. They have three valence electrons and show both metal and non-metal properties.
Boron is located in Group 13 (formerly Group IIIA) and Period 2 of the periodic table. It has an atomic number of 5.
Aluminum falls under Group 13 (formerly known as Group IIIA) of the periodic table, also known as the Boron group. It is a metallic element with the symbol Al and atomic number 13.
Elements in group IIIA, also known as group 13, have 3 electrons in their outermost shell. This is because they are located in the third column of the periodic table, which determines the number of valence electrons an element has based on its group number.
All of the elements in the boron group except boron are metals. This group, also known as Group 13 or Group IIIA, includes aluminum, gallium, indium, and thallium. These elements exhibit typical metallic properties such as conductivity and malleability.
