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 instalment is a very small piece of prevail over bea. These particular parts are the entire matter of the universe. An atom consists in general of quadriceps and is composed of tiny particles of matter. An atom is composed of 3 types of matter Protons, Neutrons and electrons. Nucleus- The dense positively charged center of an atom. Proton (P+)- placed in the inwardness 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 deaf(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 begin along of neutrons in its nucleus than it would unremarkably have. negatron (e-)- Orbiting the nucleus at advanced speeds are the electrons. Electrons are electrically controvert an d about 1/2000 the mass of Protons or Neutrons. An atom has a overall negative charge when it gains electrons to stuff its valence shell during a chemical reaction.

It is a! lso the number of electron in a neutral atom. Atomic Mass- The atomic mass is the sum of protons and neutrons. You tin frame 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 upsurge also include the second or the third letter). It enables sprightly notation... I thought that these notes were quite good. But you might necessitate to purify to put the words into basic English. If you want to get a full essay, order it on our website: OrderEssay.net
