Unformatted text preview: by an atomic symbol. Each element is composed of particles called atoms that display the characteristic properties of that element. Physical properties are things that can be detected with our senses or measured (color, texture, boiling point). Chemical properties describe how atoms react with other atoms. An atom has three subatomic particles – protons, neutrons, and electrons. The central nucleus of an atom is composed of protons and neutrons. Protons are positively charged; neutrons are neutral (no charge). The nucleus is surrounded by negatively charged electrons orbiting in an electron cloud. An atom has an overall neutral charge because there are equal numbers of protons and electrons. Elements can be identified by their atomic numbers. The atomic number is the number of protons in an element. It is written as a subscript to the left of the atomic symbol....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
