Gallium's radius is slightly than Aluminum's because Gallium has more protons than Aluminum. It sounds crazy because Gallium has more shells but u have to take into consideration that Aluminum's excited electrons actually spread through the d orbital making the radius bigger. Gallium on the other hand, has more protons, so when his excited electrons spread out it results in a lesser radius because the attraction between the protons and electrons are much bigger. It is confusing because he has a 4th shell with electrons, but since there are only 3 outer electrons (4s2 and 4p1), u can neglect it because of the big attraction of the nucleus.
I hope this helped.

What element corresponds to eka-aluminum?
Eka-aluminum corresponds to the element gallium. Gallium is located below aluminum in the periodic table and shares similar chemical properties with eka-aluminum.
Why does gallium weakens aluminum structure?
Gallium weakens aluminum structures primarily by promoting the formation of intermetallic compounds and disrupting the aluminum's crystalline lattice. When gallium is introduced to aluminum, it diffuses into the metal and can cause grain boundary embrittlement, making the aluminum more susceptible to cracking and failure. This phenomenon occurs because gallium alters the mechanical properties of aluminum, reducing its strength and ductility. As a result, even small amounts of gallium can significantly impair the structural integrity of aluminum components.
Which element is in the same group as aluminum?
I believe Gallium
What is the current name for-eka-aluminum?
gallium
Does an atom of aluminum and an atom of gallium have the same atomic mass?
No, an atom of aluminum and an atom of gallium do not have the same atomic mass. Aluminum has an atomic mass of approximately 26.98 atomic mass units, while gallium has an atomic mass of approximately 69.72 atomic mass units.
Does atom aluminum and gallium have same total of valence electrons?
Gallium possess total inner electrons
Is gallium shiner than aluminum?
After my opinion they are similar.
Would gallium react with acetic acid?
No it wold not because Gallium is in the same family as Aluminum and therefore has similar properties to Aluminum. Aluminum does not react with acetic acid.
What is another name for Gallium?
Gallus,Galij, or eka-aluminum It is also called Gallia meaning France in French or Latin
What known element corresponds to eka-aluminum on the modern periodic table?
Eka-aluminum corresponds to the element gallium on the modern periodic table. Eka-aluminum was a placeholder name given by Dmitri Mendeleev for an element that he predicted would have properties similar to aluminum but with a higher atomic mass. Gallium, discovered in 1875, fits these properties and is known as eka-aluminum's modern counterpart.
Is gallium soft or hard?
Gallium is a soft metal, similar to the hardness of common household aluminum foil. It has a low melting point and can easily be cut with a knife.
Which is the transition element among gallium nickel aluminum and tellurium?
Nickel is the transition element among gallium, nickel, aluminum, and tellurium. Transition elements are typically found in the d-block of the periodic table and are known for their variable oxidation states and colorful compounds.
