B , Al , Ga and In are same group elements.
from top to bottom atomic size increases. Because the differentiating electron enters in to new shell.
therefore Al is smaller than Ga
1. Explain why the atomic radius of Ga is smaller than Ca. You cannot merely state the trend. You must explain using Z and shielding. 2. Explain why the ionization energy of Ga is less than Ca. 3. Draw the best Lewis structures for the following species. Ensure you make the dots very clear to see. Show nonzero formal charges on the correct atoms. a) SbI4- anion b) COCl2 c) XeOF4 4. For the above species, draw the molecular geometry...
Arrange the following elements in order of increasing electronegativity. B Ga O In Al
Which type of hybrid orbitals is used in by the central atom in NO? O al sp? d) sp el spd Page 10 of 10
Arrange the following elements in order of increasing electronegativity. B=2.0 Ga=1.81 O=3.5 Al=1.5 In=1.78 looking at this the order should be Al,In,Ga,B,O But it shows as incorrect
Give the nudlear symbol for the isotope of gallium, Ga, that contains 40 neutrons per atom. Ga Replace the question marks with the proper integers. If necessary, use the button that looks like two red arrows to clear your changes and return the answer box to its original staie.
6 It is desirable to deposit a mixture of Ga and Al using a single source evaporator. If the deposition temperature is 1100oC, the mixture in the crucible is initially 50% molar and both components have sticking coefficient of one. What would the initial film composition be? How will this change with time?

He 17 Al Si P S CIAr 12 35 Zn Ga Ge As Se Br Kr 53 51 116 115 113 112 GaN is known as a IlI-IV intrinsic semiconductor. Ga has 3 electrons in its outermost shell, and N has 5. Ga and N share electrons so that each has 8 electrons, producing a completely full valence band What element could be a n-type dopant in GaN? You must also state which site (e.g. replacing Ga or N) the...
Would a helium atom get bigger, smaller, or remain the same size if one of its electrons was excited from the ground state to an excited state? Explain your reasoning.
