I just took the pre-SAT. I thought it was going to be harder than it actually was. When I took it, it took 3 hours. The first part was reading passages and answer questions about it. That was 1 hour. The next part is on grammar. You look at sentences and figure out if they used the right set of words or punctuation. That was 45 min. The 3rd and 4th part was on math. On the third part there was like 12 multiple choice questions and like 4 problems you had to work out. The fourth part had like 21 multiple questions. and 4 problems you had to work out.
Krypton (Kr) and bromine (Br) are Period 4 elements that are also called p-block elements. Krypton is a noble gas while bromine is a halogen.
While comparing the stability of the two elements, Krypton is more stable than bromine. This is because being a noble gas, Krypton follows the octet rule and maintains its stability. Bromine has 35 electrons and the outer most valence shell has 7 electrons so its unstable. Krypton has 36 electrons and 8 electrons in the valence shell so its stable.
