Copper is a ____ solid made up of atoms in a 3D ____ held together by non-____ metallic bonds. Due to the non-directional nature of the metallic ____, particles can ____ past one another without ____ the bonding, thus copper can be ____ into wires. Due to the ____ valence electrons in the structure, copper contains ____, charged particles, which allow it to ____ electricity Oxygen is a ____ substance. The molecules are held together by ____ ____ forces. These forces require only a ____ energy to overcome, turning oxygen into a ____; therefore the ____ of oxygen is low. Graphite is a 2D-extended ____ substance. It consists of ____ of carbon atoms, bonded into ____ by strong ____ bonds. These bonds require a ____ of heat energy to ____ and therefore graphite only turns into a ____ at ____ temperatures. The strength of ____ between ____ in each substance is what determines the temperature required to form ____ substances. Water is a ____ solvent, while cyclohexane is a ____ solvent. As ____ is non-polar, the ____ forces it forms with water molecules are ____ than the existing ____ found between particles within both the ____ and solute. However, as both kerosene and cyclohexane are non-polar ____, the attractions that form ____ cyclohexane and kerosene ____ are strong enough to ____ attractive forces within each substance, allowing kerosene to ____. N2O has ____ of electron density around the central ____, These regions arrange with ____ to ____, giving N2O a parent geometry of linear and a bond angle of ____. N2O has two bonding and ____ regions so an overall ____. Meanwhile, hydrazine has four regions of ____ around the N atom. N2H4 has a parent geometry of ____ and a bond angle of ____ about ____ N atom. N2H4 has ____ and one non-bonding regions about each nitrogen atom, giving an ____ of ____. Both the P–Cl and B–Cl bonds in ____ are ____ due to the ____ in ____ between atoms. In PCl3, the ____ are arranged ____ due to the ____ pyramid shape, meaning the ____ and the molecule is polar.
