Explain what is going on from a molecular point of view. See meter African right. A sheet of paper is about six orders of magnitude thicker than an atom. First you will can sell for a bunch of e Bye from humility in the denominator. The periodic table is a reference to be used, not memorized. Appendix $E$ describes a useful study aid known as concept mapping. Boron has primarily two isotopes, one with an atomic mass of 11 amu and another with an atomic mass of 10 amu. There are several ways of solving this problem that give somewhat different answers, any is OK. If an atom were the size of a baseball stadium, the nucleus would be the size of a fly in the center field, and the electrons would be like two tiny gnats buzzing around the stadium. How big would the nucleus be of the atom was the size of an Olympic swimming pool? 54) An element has two different isotopes: one that weighs 65 amu and another that weighs 67 amu. If the abundance of the boron atom with a mass of 11 amu is 18.9 percent and the abundance of the other isotope is 81.1 percent, what would be the average mass of the boron atom? 107) The shell model presented in this book is not very accurate.

Using common objects that people are familiar with is better than using abstract landmarks that are difficult to imagine. The order of magnitude is -9, so the diameter of the atom is nine orders of magnitude smaller than the battery. For heavier atoms, they would extend to about 36 times farther than Pluto. What do the electron configurations for all the group 18 noble gases have in common? That's what the hell I knew What it is off dumb, is it? atoms to support the functions that they need to carry out. A. element with the same number of protons but a different number of neutrons. Yes. 125) Since atoms are mostly empty space, why don t objects pass through one another? Most of the space in an atom is Typically the nucleus contains more than 99.9% of the mass of the atom. Electrons are outside of the nucleus but bound to it by electromagnetic force; protons and neutrons are packed tightly inside, held together by a force thats roughly 100 times stronger than electricity the strong force, its called. A quick primer on the atom: Atoms are composed of protons, neutrons and electrons. If the atom were the size of a baseball stadium, the nucleus would be smaller than the baseball.
