Atomic Structure Chm 1.1.1
Compounds Elements that are CHEMICALLY bonded together Can’t be separated by physical means
Elements Made up of 1 type of atom
Atoms Smallest unit of matter That has the characteristics of the element What elements are made of
Regions of the Atom Nucleus Electron Cloud -Area surrounding the nucleus
Nucleus Subatomic Particles: Proton – mass = 1amu positive charge Neutron – mass = 1amu no charge
Electron Cloud Subatomic Particle: Electron – mass = 0 amu negative charge orbits the nucleus
Ions + An atom with an electrical charge cation
Ions - anion
Isotopes Different number of neutrons = different mass
Isotope Designation Carbon - 12
Atomic Number, Mass # and Atomic Mass Atomic Number Atomic Mass Mass Number = 59
Reviewing Subatomic Particles
Atoms Chapter 2, Section 1.
Chapter 11 Matter and Its Properties
Inside an Atom.
Atomic Structure Section The Nucleus Nucleus- contains most of the mass of an atom – Protons & Neutrons contains most of an atom’s mass – Electrons-
Atomic Structure Nucleus – contains protons and neutrons
Structure of an Atom.
Structure of an Atom. What Is an Atom? An atom is often referred to as the building block of matter. Atoms have a nucleus surrounded by an electron cloud.
Atoms 8.5A The student is expected to describe the structure of atoms, including the masses, electrical charges, and locations, of protons and neutrons.
Atoms Atomic Mass/Number Ions/Charges of Molecules Isotopes/Perc ent Abundance
Components of the Atom Nucleus: Nuclear Forces:
Chemistry of Life Biology Chapter 2.
Atoms and Molecules Atom is smallest particle that can be identified as a particular substance. Molecule is two or more atoms bonded to each other.
Matter & The Atom. Matter The term matter describes all of the physical substances around us Matter is anything that has mass and takes up space The Universe.
Warmup: Concept: PS-2.1 Compare the subatomic particles.
ATOMS Basic building blocks of all matter.
