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.
Hello
We can approach science from various angles. It may be that our aim is to solve a problem or to try to understand something. But, at the same time, what we find in it as explanatory or credible may be different if our profession is to be a trader, an importer of industrial equipment, a researcher or a teacher. Our concerns about science may differ according to the angle from which we think about it. That is to say, what is important when judging or evaluating science is different according to our relationship with it at certain times: whether we see it as producers, disseminators or consumers. Therefore, from the outset we have an area of complexity in thinking about science from our starting point.
Solar system is the answer. i believe.
