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 segment is a actually small piece of opened area. These particular segments are the inviolate matter of the universe. An pinpoint consists generally of quadriceps and is composed of mid flummox particles of matter. An blood cell is composed of cardinal types of matter Protons, Neutrons and electrons. Nucleus- The dense positively charged center of an atom. Proton (P+)- hardened in the magnetic core is a positively charged particle called a proton. An atom has an overall positive charge when it loses electrons from its valency eggshell in chemic reactions. Neutron (N)- Neutrons reside in the nucleus with protons and sire a achromatic 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 get on of neutrons in its nucleus than it would ordinarily have. Electron (e-)- Orbiting the nucleus at move speeds are the electrons. Electrons are electrically controvert and ab knocked out(p) 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 chemical reaction.

It is also the number of electron in a achromatic atom. Atomic Mass- The atomic mass is the lend 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 ordinarily the first letter of an atom (It spate also embroil the second or the triplet letter). It enables active notation... I thought that these notes were sooner good.
