Use your periodic table of elements. take any element of your choosing (from period 4 or above) and answer the following questions: ( i choose silicon) what is the element's name and symbol? is it a metal, nonmetal, or metalloid? which family does it belong to? how many protons, neutrons, and electrons does its neutral atom have? !

Silicon's element name is Silicon. Silicon's symbol is "Si" Silicon is a metalloid. Silicon would belong in the Semi-Conductor's family. 14 Protons, 14 Neutrons and 14 Electrons (if the silicon element is neutral and the most common of it's atom.)

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
