Sodium Chloride Magnesium Oxide
simple molecules are bonds between non-metals and elements, or in some cases, non-metals and non-metals. Things like Water, CO2, I2 are simple moleculars. The single molecules of simple moleculars are held together through covalent bonds, the intermolecular forces that hold together many bonds are weaker, thus simple moleculars have low melting/boiling points. Giant Metallics are bonds between metals, such as Zinc Magnesium, and have strong bonds among and between atoms, with high melting/boiling points and ability to conduct electricity.
it is a simple structure
Sodium, magnesium and aluminum are all good conductors of electricity. Silicon is a semiconductor.Sodium, magnesium and aluminum all have metallic structures, which accounts for their electrical conductivity and relatively high melting and boiling points.The nuclei of the atoms gets more positively charged.Melting and boiling points rise across the three metalsSilicon has the highest melting point.Phosphorus, sulphur, chlorine and argon are simple molecular substances with only van der Waals attractions between the molecules. Their melting or boiling points will be lower than those of the first four members of the period which have giant structures.These four substance with simple molecular structures also do not conduct electricity.
simple molecular compounds have weak forces of atraction.
Magnesium Bromide has a giant structure
Sodium Chloride Magnesium Oxide
They are covalent. Some are simple molecules, others are giant covalent structures.
Chemical formula of potassium bromide is KBr. Potassium and bromide ions make a giant lattice. It is very hard.
It depends on the type of structure; simple covalent structures (like water) generally have low boiling points, while giant covalent structures (like diamond) have high boiling points.
Yes, metallic bonds only ever form giant structures. Mercury is an exception to the rule that giant structures have high melting points.
