Seahawk Matter Chp 1
Irwin Interaction with Matter Chp 1 Notes
| Question | Answer |
|---|---|
| Chemical Bonding | The combining of atoms to form molecules |
| Chemical Bond | An interaction that holds atoms or ions together |
| Valence Electron | An electron that is found in the outermost shell of an atom and that determines the atom's chemical properties. |
| Ionic Bond | a bond that forms when electrons are transferred from one atom to another, which results in a positive ion and a negative ion. |
| Ion | a charged particle that forms when an atom or group of atoms gains or loses one or more electrons. |
| crystal lattice | the regular pattern in which a crystal is arranged. |
| covalent bond | a bond formed when atoms share one or more pairs of electrons. |
| molecule | the smallest unit of a substance that keeps all of the physical and chemical properties of that substance. |
| metallic bond | a bond formed by the attraction between positively charged metl ions and the electrons around them. |
| Which electrons are used to form bonds? | Most atoms form bonds only with their valence electrons. |
| The atoms from which group in the periodic table rarely form chemical bonds | Atoms in Group 18 (the noble gases) rarely form chemical bonds. |
| Why are atoms neutral? | Atoms are neutral because he number of protons in an atom always equals the number of electrons in the atom. |
| Atoms of which group on the periodic table give off the most energy when forming negative ions? | Atoms in group 17 give off the most energy when forming negative ions. |
| What is a covalent bond? | A covalent bond is a bond that forms when atoms share one or more pairs of electrons. |
| How many atoms are in a diatomic molecule/ | There are two atoms in a diatomic molecule. |
| What is ductility? | Ductility is the ability to be drawn into wires. |
