Aluminum has a larger radius than Boron because there are more electron filled 'orbitals' around its nucleus. Atomic radius increases down a group for that reason.

Why is the atomic radius of Al and Ga same?
RGUKT IIIT NUZVID:N091528 The atomic radius of the Ga is less than Al because of poor screening effect The atomic radius of Ga is slightly lesser than of Al because in going from Al to Ga, the electrons have already occupied 3d sub shell in Ga. The screening effect of these intervening electrons being poor and has less influence to decrease the effective nuclear charge, therefore the electrons in Ga experience more forces of attractions towards nucleus to result in lower size of Ga than Al
Which element has larger atomic size Fe or Ni?
Ni (Nickel) has a larger atomic size than Fe (Iron). This is because Nickel has more electrons and energy levels, which leads to a greater atomic radius compared to Iron. Additionally, Nickel is located in the same period as Iron on the periodic table, but it is to the right of Iron, indicating a larger atomic size.
Why the group tend of IIIA group is not regular?
because in IIIA group d-orbital interduce so Ga has greater I.P value than Al and the atomic radius of Boron and Al are nearly about same and ionic radius of Al and Ga are nearly about same as a result there is not regular change occurs in the properties of IIIA group.
Why does Europium and Ytterbium show an anomaly when considering the trends of Lanthanide atomic radius across the group?
lanthanide contraction, or f-block contraction.Source:http://facultyfp.salisbury.edu/dfrieck/htdocs/212/rev/table/size.htmIn the data given for group 13 there is an interesting deviation from the expected trend for atomic radius. At first, we might expect that an atom of Ga would be larger than an atom of Al based on their positions in group. Gallium, however, is considerably smaller than Al due to a phenomenon known as the d-block contraction. As explained above, atoms get smaller as we progress from left to right across a given period, thus in period three Na is larger than Mg, Mg is larger than Al, Al is larger than Si, etc., until we arrive at Ar, the smallest atom in row. The next element, K, is in period four and is, as expected, larger than any period three atom. Again, as we progress to the right atomic radius decreases due to increasing Zeff. It is in period four, however, that we first encounter the transition elements. Atomic radius decreases as we move from Sc to Ti to V, etc., as electrons are added to the d-subshell. By the time we completely fill the d-subshell and reach the p-block elements, the atomic radius has decreased so much that Ga is actually smaller than Al. Because of the d-block contraction, the post transition elements of period four are about the same size as their period three congeners. Similarly, the occurrence of the f-block elements between the period six s- and p-blocks causes the period six p-block elements to be about the same size as their period five congeners. This effect is called the lanthanide contraction, or f-block contraction.
Which element having atomic number 13?
The element with the atomic number 13 is aluminum.
What is the largest radius Na or Al?
Sodium has a larger atomic radius than aluminum.
Which has the largest atomic radius li or be?
Lithium has a larger atomic radius than hydrogen.
What is larger than the atomic radius of P?
There are many elements with atomic radii larger than that of P. Several examples would be Si, Al, Mg, and Na.
Which element has a larger radius Al or F?
Al

Which is bigger in size aluminum atom or chlorine atom?
Elements atomic radii increase in size as they run down the columns of the periodic table or across the periodic table from right to left. So, Al is larger than Cl. XP
What atom has the largest atomic radius between Al and Ti?
Ti
Largest atomic radius out of Ca Na Fe Al and k?
K
Which of the following has the smallest atomic radius P AL S Si Cl?
Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
Why is the first ionization energy of aluminium is less than the first ionisation energy of silicon?
Al has atomic number 13, and silicon has atomic number 14. The extra electron that silicon has is in a 3p orbital. In simple terms the extra charge on the silicon nucleus contracts the electron shell, this increases the energy to remove an electron and also decreases the atomic radius. Al, first ionization energy 577.5 kJ/mol, atomic radius 125pm Si, first ionization energy 786.3 kJ/mol, atomic radius 110pm
What neutral atoms has the largest atomic size betwee K Al S and Si?
From the given elements, potassium has the largest atomic radius.
