The first 5 ionisation energies in KJ MOL of aluminium are578 1817 2745 11578 14831The orbitals from which the first 5 electrons are removed during ionisation energies, starting with the first electron are1) 1s 2s 2p 3s 3p2) 1s 1s 2s 2s 2p3) 3p 3s 2p 2s 1s4) 3p 3s 3s 2p 2p The answer is number 4.I need an explanation please! thanks!!
wow 5'11 at 13 are you sure you don't mean 4'11 Anyway the best way to lose any weight is cardio cardio CARDIOIt's a bother to me but if you have a friend willing to go jog with you it makes it a lot easierGood luck!
You are 13, and from your description it is probably baby fatJust eat healthy and exersize and that's all you need to do, don't do anything drastic to try and lose weight, your body is still developing, just eat well and do 30-45 minutes of excersize most days a week.
the electronic struture of aluminium Z13 is 1s2 2s2 3p6 3s2 3p1 for elements under Z19, the rule of energy bonding of one electron to the nucleus is the lowest bonding for subshells having the highest first quantic number and the highest second quantic number so the electron 3p has the lowest energy and is removed firstafter you remove the two electrons 3s and after 2 electrons 2p
Just change your eating habits try eating under 1,200 calories a day and excerise for 30 mins a day good luck
I've lost 5 kilos in my first weekIt's my 10th day and I have included salad with some protein (egegg/ lean chicken) as you suggestedAfter 4 years of trying, the fat is finally coming offIt truly feels like magic! Get started today!
