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. |
