Why do metals conduct heat so well?The electrons in metal are delocalised electrons and are free moving electrons so when they gain energy (heat) they vibrate more quickly and can move around, this means that they can pass on the energy more quickly.Which metals conduct the best?
不是所有的金属 都具有同样好的导电性能。( ) All metals do not conduct electricity equally well.A.正确B.错误
Do nonmetals gain or lose electrons? Do nonmetals conduct heat and electricity? What does the electronegativity of an element indicate? Which element has the highest electronegativity? Do ionic bonds occur between metals and nonmetals? What is the electronegativity of neon?
In what form can an ionic compound conduct electricity? What happens to electrons in ionic bonds? How do ions form ionic bonds? Could two atoms of oxygen engage in ionic bonding? Why or why not? Do nonmetals conduct heat and electricity?

Do nonmetals conduct heat and electricity? What happens when nonmetals react with water? Why does the oxidation number change for elements with multiple oxidation states and what happens to those electrons? What are some chemical properties of nonmetals? When nonmetals bond with other atoms, what...

Metals are elements that tend to have a shiny appearance, conduct heat and electricity well, are malleable and ductile, and tend to lose electrons to form positively charged ions. Nonmetals, on the other hand, tend to have dull or gas-like appearances, poor heat, and electrical conductivity,...
With reference to covalent and ionic bonds. why does protein not dissolve in water as salt does? Which bond is stronger, ionic or covalent? How can I differentiate between ionic and covalent compounds? Why does solid calcium conduct electricity but solid iodine does not?
