High melting and boiling point
WebVery high melting points – this is because a lot of strong covalent bonds must be broken. Graphite, for example, has a melting point of more than 3,600°C. Variable electrical conductivity... Webmelting and boiling points increase with: increasing atomic/molecular size why do larger atoms have a higher melting and boiling point? In a larger atom, the valence electrons are, on average, farther from the nuclei than in a smaller atom. Thus, they are less tightly held and can more easily form the temporary dipoles that produce the attraction.

WebIonic and Covalent compounds are two broad categories of chemical compounds that are distinguished based on the type of chemical bond present between the atoms in the compound. The properties of these compounds, including boiling point, melting point, solubility, and conductivity, are greatly influenced by the type of bond present. WebHigh melting and boiling points - ionic bonds are very strong and a lot of energy is needed to break them, so ionic compounds have high melting points and boiling points. Conductive when liquid - ions are charged particles, but ionic compounds can only conduct electricity if their ions are free to move.
WebA liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100°C (212°F) at sea level, but at 93.4°C (200.1°F) at 1900 metres (6,233 ft) altitude. ... As with boiling points, the melting point of a solid is dependent on the strength of those attractive forces. For ...

WebThe high melting and boiling points of d-block elements are generally based on how strong the metallic bond is between their atoms. In any molecule, a metallic bond contains a higher number of unpaired electrons. Therefore, the metallic bond present is stronger, and the melting or boiling point is higher. When we move from left to right in the ...
