Chemistry

3. Atoms tend to gain, lose or share electrons so they have 8 electrons
4. What types of elements are found in a ionic compound
7. Dissolve easily in water and other polar solvents
11. Indicates the relative number of atoms of each kind in chemical compounds
14. ions can form from isolated atoms and by electron transfer between atoms of different elements
16. What type of electrons are able to participate in chemical bonds
17. which elements have stable electron configurations
19. When different atoms in 2 different compounds trade places
20. how does the name change in a ionic compound
21. Ionic compounds that form this structure
23. is related to the number of valence electrons on the atom

1. an attraction between atoms that allows the formation of chemical substances that contain two or more atoms
2. An atom with more or less electrons than protons
5. drawing that shows valence electron movement between atoms
6. Number assigned to an element in chemical combination that represents the number of electrons lost
8. an electron moves from an atom or a chemical species to another atom or chemical species
9. valence of an ion is the coefficient that, when multiplied by the elementary charge, gives the ion's charge.
10. Metals lose their valence electrons to form positive ions
12. the energy required to completely remove an electron from a gaseous atom or ion.
13. When one element replaces another on in a compound
15. Non metals gain valence electrons to form negative ions
18. 2 or more elements or compounds combine to make a more complex substance
19. Compounds break down into simpler substances
22. formation formed between ions with opposite charges
