Document Summary

1. 0 x 10-9 cm: 1089 microliters to milliliters 1. 089 ml, name the elements based on the given information, the nucleus has 32 protons. Cerium: there are 45 electrons in a neutral atom. Rhodium: there are 17 electrons in a 3+ charged cation. Calcium: there are 12 electrons in a 1- charged anion. Sodium: the mass number is 57 and there are 9 neutrons. Cadmium: describe the characteristics of particles in each state of matter. Solids: have a constant shape due to particles being trapped together through the bonds made from the particles being strongly attracted to each other. Liquids: have a constant volume but a shape that may change. This is due to the particles being able to move fast enough where the attractions between them may break. Particles move around but not as fast as gas. Gases: has a variable shape and volume where there is a large distance between particles.
