Why has magnesium got a high boilign point?
Magnesium has a high boiling point due to its strong metallic bonding. In a metallic structure, magnesium atoms are held together by strong forces of attraction, requiring a significant amount of energy to break these bonds and change the state of matter from solid to liquid.
How can the strength of metallic bonding be measured?
The strength of metallic bonding can be measured through various methods such as tensile testing, hardness testing, and electron microscopy techniques. These methods help in quantifying the forces that hold metallic atoms together in a solid structure, providing insights into the strength of the metallic bond.
How does the bonding effect the macroscopic properties of the molecule?
The type of bonding in a molecule (ionic, covalent, metallic) affects its macroscopic properties such as melting point, boiling point, and conductivity. Stronger bonds typically result in higher melting and boiling points, while compounds with covalent bonds are usually poor conductors of electricity compared to ionic compounds. The nature of bonding also influences the structural arrangement of molecules and their physical properties.
Why is the melting point of Bi lower than Sb and the melting point of Sb lower than As?
The melting point of elements generally increases going down a group in the periodic table due to increased atomic size and therefore stronger metallic bonding. However, in the case of Bi, its anomalous behavior is attributed to the presence of inert pairs that reduce metallic bonding. This makes the melting point of Bi lower than Sb, which follows the trend of increasing melting points down the group due to stronger metallic bonding. The same trend applies to Sb having a lower melting point than As due to the weaker metallic bonding in Sb compared to As, which also follows the trend of increasing melting points down the group.
Which type of bonding is characteristic of a substance that has a high melting point and electrical conductivity only in the liquid phase?
The substance would likely exhibit metallic bonding. Metallic bonding is responsible for high melting points due to strong bonding between metal atoms. Electrical conductivity in the liquid phase occurs because the metal atoms are mobile and able to carry electrical charges.

What is the melting point for a metallic bond?
it is extremely high....over 15 degrees Fahrenheit

Why there is a difference in the boiling point of titanium?
To properly answer this question you must discuss these things 1. particles 2. the arrangement of the particles 3. the type of bonding 4. the properties ANSWER: Titanium is a metallic solid. It is made up of atoms. Titanium consists of a network of positive ions surrounded by a sea of freely moving delocalised valence elctrons. The type of bonding that takes place in titanium is metallic bonding which is a very strong type of bond. Metallic bonding is the bond between the positive ions and the delocalised electrons. Titanium has a high melting point because the strong metallic bonds between the ions and electrons require a large amount of energy to break them. Therefore they have a high melting point.

What happens during metallic bonding?
Metallic bonding is the electrostatic attraction between postive metal ions and the delocalised electrons surrounding them. Theese forces are very strong which is why metals have very high melting points. The more charge a ion has will increase its melting point as the electrostatic attraction will be higher.

What is the boiling point of a metallic bond?
Unfortunately I cannot answer your question. Something You Should Know: EVERY SINGLE BOILING POINT DOES DEPEND ON MOLECULAR BONDING; BUT THE BOILING POINT DEPENDS ON THE COMPOUND AS A WHOLE. HOW MANY METALLIC BONDS ARE THERE? WHAT KIND OF METAL IS INVOLVED? HOW IS THE BOND SITUATED AMONG THE REST OF THE BONDS? IS THE METALLIC BOND A HIGHER PRIORITY THAN OTHER BONDS? WHAT OTHER ELEMENTS ARE INVOLVED IN THE COMPOUND?
Why do plastics have a lower melting point than metals explain in terms of chemical bonding?
Plastics have weaker intermolecular forces such as van der Waals forces or hydrogen bonds, compared to the strong metallic bonds in metals. These weaker forces in plastics require less energy to break, resulting in a lower melting point. The strong and directional bonding in metals, on the other hand, requires more energy to break and thus they have higher melting points.
Why tungsten has a high melting point?
The metallic bonding between the 5d electrons , 5 of them unpaired makes the bonding strong enough to make it have highest melting point. Though Cr and Mo have similar conditions but the lanthanide contractions aid to W.
Why does Cu have a greater boiling point than methanol CH3OH?
Cu has a lower boiling point than CH3OH because its particles are less polar. the CH3OH molecules have to have more kinetic energy to break the bonds between them and the surrounding molecules.
