Chemistry Exam Yr 10

What are Subatomic Particals Electrons, Protons and Neutrons
How do you work out Nurtons? Neutrons= mass - atomic
How do you work out Protons Protons= atomic number
What is a Neutral Atom Same number of Electrons and Protons
John Daltons Law 1 All matter is made of Atoms
John Daltons Law 2 Atoms of an element are identical
John Daltons Law 3 Atoms of Diffrent elements combine in constant ratios to form compounds
John Daltons Law 4 Atoms are rearranged in reactions
What is Matter Matter is anything that takes up Mass
What is a Atom The smallest partical of an element that retains the propaties of that element
What is an Electron The negativly charged subtomice partical
What is an Proton A positive charged subtomic partical
What is a Neutron A subtomic Partical with no charge
What is a Neucleus Center of an atom which is composed of atoms and protons
Element Diagrams how many dots in each ring first 2 second 8
Diffrence between reactunts and products? Starting chemicals are reactunts and the finishing product is the product
What are ionic Modules More than one atom joined togethere.g metal and non metal (steals)
What are Covelent Compounds Two Non metals were they share
How to write the name for an Ionic Compound If the anion in an ionic compound is an element then the name of the compound ends in ide.
What does valancy mean? Is the number of electrons an atom must gain or lose or share to complete its outershell
What are cations Atoms in group 1a2a3a that have to lose electrons and have a positive charge
What are Anions Atoms which gain electrons in group A's in the non metals which have an negative charge.
What is an combination Is when 2 or more reactunts are joined and equals one product A+B=C
What is and Decompostion Is when an reactunt equals 2 products so the reactunt is broken into smaller parts. AB=A+B
What is an Single Replacment Is when a replaces b and ends up with B+ACElement+ Compund = Compound + Element
What is a Double Replacment Is when both partners swap with each otherAB+CD=AD+CB
Law of Matter Matter can not be made or destroyed it is simply transformed
