Which of the following is not a characteristic of a covalent compound? A) It can be a solid, liquid or gas B) It has a low melting point C) It is made of two nonmetals. D) It is formed when metal atoms lose electrons to nonmetal atoms.
I think its D but I have no idea..
@bakonloverk @BrittanyFrench @dusty @redred413 @thatgirlisheres @Tylers_Babygirl101 can you please help me with this? :)
please im realy confused on this :/
A.) it can be a soild, liquid or gas . Following are the typical characteristics of covalent compounds: (i) Low melting and boiling points: Covalent compounds consist of molecules held by weak forces. These can be easily overcome by heat. Thus, covalent compounds have low melting points and low boiling points. (ii) Non-conducting nature: Covalent compounds do not conduct electricity, i.e., electricity does not pass through the covalent compounds. This is because the covalent compounds do not contain ions, or free electrons. Sugar is a covalent compound, and its solution does not conduct electricity. Solutions of polar covalent compounds, e.g., HCl, conduct electricity due to the presence of ions in solutions. (iii) Solubility: Covalent compounds are usually insoluble not polar solvents like water. The covalent compounds however, dissolve in non-polar solvents, like benzene, toluene, etc. (iv) Slow rate of reaction: the reactions of the covalent compounds are quite slow. This is because the covalent compounds take part in reactions as molecules, and the molecular reactions are slow. (v) Isomerism: Covalent bonds are rigid and directional. Therefore, these can give different arrangements of atoms in space. So, a single molecular formula may represent a number of different compounds with different properties. This phenomenon is called isomerism.
thank you...I understand it now :)
your welcome and thats good :)
