The radius of an atom of aluminium, in the ground state, is 118 picometres = 1.18*10^-10 metres = 11.8 angstrom.
1.43 A0
Sodium has a larger atomic radius than aluminum.
K
Lithium has a larger atomic radius than hydrogen.
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
chlorine. across a period the size decreases
Al
Sodium has a larger atomic radius than aluminum.
Sodium
Ti
K
Lithium has a larger atomic radius than hydrogen.
The formula is AL = 2*Pi*radius*height
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
The answer is 226.19 units2The formula is AL = 2*Pi*radius*height
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.
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
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.
