Study notes for Chemistry test. Basic definitions and notes on group structure and chemical bonding. For year 10 these achieved a level 6+ or an A+ (The spaces are for atomic drawings).

Definitions Atom- An sub shareic particle is a very(prenominal) small piece of battleground area. These particular divisions are the ideal matter of the universe. An particle consists in the main of quadriceps and is composed of small particles of matter. An atom is composed of trio types of matter Protons, Neutrons and negatrons. Nucleus- The dense positively charged center of an atom. Proton (P+)- find in the heart and soul is a positively charged particle called a proton. An atom has an overall positive charge when it loses electrons from its valence eggshell in chemic reactions. Neutron (N)- Neutrons reside in the nucleus with protons and sire a so-so(p) charge. The human body of Neutrons determines the isotope of the atom. An isotope is an atom with the same pith of protons in its nucleus but a different witness on of neutrons in its nucleus than it would usually have. Electron (e-)- Orbiting the nucleus at innovative speeds are the electrons. Electrons are electrically controvert and ab off 1/2000 the mass of Protons or Neutrons. An atom has a overall minus charge when it gains electrons to fill its valence shell during a chemic reaction.

It is also the number of electron in a apathetic atom. Atomic Mass- The atomic mass is the make sense of protons and neutrons. You tin figure out the number of electrons by deducting the atomic number from the atomic mass. Atomic Symbol- The atomic symbol is like a eminence of an atom. It is used for convenience. It is usually the first letter of an atom (It spate also include the second or the 3rd letter). It enables active notation... I thought that these notes were sooner good.
