Boron (B) 17. Which of the group IIIA (13) elements has the largest ionization energy? Astatine (At) 18.
Which of the group 13 elements is the largest?
While, aluminum, indium, and thallium have typical metal properties, gallium has the largest liquid range of any element. Boron exists as a molecular compound in the solid state, hence its high melting point.

Which element in each pair has the higher ionization energy?
Which element in each pair has the larger first ionization energy? Sodium has the larger first ionization energy and in the second pair, Phosphorus has the largest first ionization energy.
Which element in Group 2 has the highest ionization energy?
As we know that ionisation energy decreases as we go down the group… So in 2nd group first comes Be (Beryllium)… So it has highest ionisation energy…
Which element in the second period has the greatest first ionization energy?
And thus neon, with the greatest nuclear charge of the 2nd period, has the corresponding greatest ionization energy of the Period. Clearly, this property is shared by all the Noble Gases.
What is Group 13 called?
Boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
Why does boiling point decrease down Group 13?
Hence, boiling point should increase down the group from boron to thallium. But in my book, the answer given is that the forces of attraction decrease down the group because of the increase in size of atoms down the group. Hence, the boiling point decreases down the group.
Which element has the largest atomic radius?
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
What is the order of increasing ionization energy?
The general trend of ionization energy is increasing from left to right and bottom to top (following the atomic radius trend), which means that the bottom left elements would have the lowest ionization energy. Based on that information, the correct arrangement would be In < Sn < Te < Xe.
What type of element loses electrons?
Elements that are metals tend to lose electrons and become positively charged ions called cations. Elements that are nonmetals tend to gain electrons and become negatively charged ions called anions. Metals that are located in column 1A of the periodic table form ions by losing one electron.
Which has lowest first ionization energy?
From this trend, Cesium is said to have the lowest ionization energy and Fluorine is said to have the highest ionization energy (with the exception of Helium and Neon).
Why second ionization energy is higher than first?
An element’s second ionization energy is the energy required to remove the outermost, or least bound, electron from a 1+ ion of the element. Because positive charge binds electrons more strongly, the second ionization energy of an element is always higher than the first.
Do metals have high ionization energy?
Encyclopædia Britannica, Inc. Metal atoms lose electrons to nonmetal atoms because metals typically have relatively low ionization energies. Metals at the bottom of a group lose electrons more easily than those at the top. That is, ionization energies tend to decrease in going from the top to the bottom of a group.
What has the highest ionization energy?
The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.
What group has the lowest ionization energy?
The group of elements which have the lowest ionization energy are the alkali metals.
What element in the second period has the largest atomic radius?
The element in the second period that has the largest atomic radius is the Lithium (Li). The answer is letter D. As you go down the periodic table, the atomic radius increases and as you go across the periodic table, the atomic radius decreases.
