| Question | Answer |
|---|---|
| What type of atoms can create metallic bonds? | Only metals |
| What happens in an ionic compound? | The atoms are held together with the TRANSFER of electrons from the metal to the nonmetal. |
| What type of compound has at least one metal and one nonmetal? | an ionic compound |
| How are atoms in covalent compounds held together? | They SHARE electrons |
| What type of bond is formed between only nonmetals? | covalent bonds |
| What do elements in the same group have in common? | They all have the same number of valence electrons |
| What element only needs 2 valence electrons to have a full valence shell? | Helium |
| What do atoms share, gain or lose when they are bonding with other atoms? | electrons |
| What is special about noble gases? | they have a full valence shell so they don't normally bond with other elements |
| Which electrons are take part in chemical bonding? | only the valence electrons |
| How are electrons in an atom organized? | in energy levels |
| What is an ion? | when an atom gains or loses at least one electron and becomes either positively or negatively charged |
| What is an ionic bond formed? | When one metal atom transfers and electron to a non metal atom |
| When does an atom have a negative charge? | When it gains electrons |
| What is the atomic number? | the number of protons an atom has |
| What is the most number of electrons that can be in the second and third energy levels? | 8 |
| What is the maximum number of electrons that can be in the first energy level? | 2 |
| What is a chemical bond? | a chemical interaction that holds 2 atoms together |
| Because metallic bonds allow the electrons to change shape, what can metals do that others cannot? | bend into different shapes without breaking |
| Who arranged the periodic table by atomic number? | Henry Mosely |
| What is ductility? | ability to be drawn into thin wires |
| If an element can reflect light and looks shiny, it is said to have what ? | luster |
| What is electrical conductivity? | the ability to carry and electric current |
| What is malleability? | the ability to be bent, hammered or rolled into thin sheets without breaking |
| Which electrons are involved in chemical bonding? | valence electrons |
| What is the periodic table? | chart of elements arranged in rows and columns according to their atomic number and properties |
| What is the row on the periodic table called? | period |
| What are the columns on a periodic table called? | groups |
| What is a electron dot diagram? | a model that shows only the valence electrons as dots around the chemical symbol |
| What is Dimitri Mendeleev know for? | trying to arrange elements in a pattern using their atomic mass |
