1)The first inonization of energy of aluminium is much lower than expected.Explain why; in your answer you must define ionization energy and use the electron configuration of aluminium.2)The ionization energy for oxygen is not as positive as would be expectedIs it easier or harder to remove an electron? why?3)write a set of quantum numbers for Co and Co2+.
Yep, our cats are 5 and 7 years old themselves, and they stll do the 'nursing' thingIt's actually kind of endearing after all these years! I think that it's just something that cats do, enjoy it!
Cats do this to recapture those kitten feelings of peace, contentment and security when they were nursing at their momma cats' bellyThe habit is normal and tends to lessen as the cat matures (depending on the cat's natural temperament)My 9 yr old cat used to knead my belly and lap until he was 3, gradually weaning himself from the habit.
Its familiarMost cats continue to knead before they sleepIt's a learned response from being a kittenMy 13 year old short haired still kneads her blankets before she sleepsIt's conforting to themMost kittens remember that nursing was a time when they were happy and safe because their mother was there to take care of themNow that your their mother they feel safe and comfortable therefore they revert to the only action they have learned in that situation The sucking may stop after a while, but the kneading tends to stay.
electron config for aluminum 1s^2 2s^2 2p^6 3s^2 3p^1 ionization energy is the energy required to remove the first electron from the atomThe 3p orbit is higher in energy than the 3s, further away from the nucleus so it is easier to remove an electron from itIn oxygen, you are now starting to double up the electrons in the p orbits, so harder to remove now.
