- 1atomsmall particles that all matter is made of
- 2electronvery small negatively charged atoms
- 3protonpositively charged atoms
- 4neutronsuncharged atos inside the nucleus
- 5describe an atomvery small particles that all matter is made of
- 6name the three particles found inside an atomsprotons, neutrons, electrons
- 7How does an atom wants to have a full valence shell and what does it become after?by losing or gaining electrons, an in doing so will form an ion
- 8ionan atom that has either lost or gain an electrons
- 9explain why atoms are electrically neutral.atoms are electrically as they have the same amount of positive and negative atoms
- 10what does metals form in and how?metals form positive ions when they lose their valence electrons
- 11explain why beryllium and magnesium form ions with the same chargeBe- 2,2
Mg- 2,8,2
both elements have two valence electrons. These electrons are lost in the reaction, so both elements gain a 2+ charge - 12what are positive ions called?cations
- 13what are negative ions called?anions
- 14how does an ionic compound formed?when a cation and an anion bonds, forming an ionic bond. this means that when a metal and anon-metal reacts together, an ionic compound form
- 15what are the polyatomic ions?Ammonium
Hydroxide
Nitrate
Hydrogen carbonate
sulfate
carbonate - 16what are the atoms that make up Ammoniumnitrogen and hydrogen atoms
