Organic compounds tend NOT to be ionic - there are exceptions. Organic Chemistry is defined as the Chemistry of Compounds of Carbon. Ionic forces tend to intercede when we add Oxygen.
Carbon normally forms four covalent bonds in its compounds, not ionic bonds.
Many ionic compounds exist as crystals but covalent compounds as molecules (there are exceptions as diamond though). Ionic compounds would be good electrical conductors unlike molecular compounds.
Ionic bonds are strong enough to cause almost all ionic compounds to be solid at room temperature.
Ionic bonds are very weak, and ionic compounds are very weakly held together chemically.
No, binary ionic compounds do not have covalent bonds where electrons are shared. Instead, they have ionic bonds where electrons are transferred from one atom to another. This results in the formation of positively charged cations and negatively charged anions that are attracted to each other due to their opposite charges.
Compounds that do not likely have ionic bonds are covalent compounds, which involve the sharing of electrons between atoms rather than the transfer of electrons. Examples include water (H2O), methane (CH4), and carbon dioxide (CO2).
Table salt is a solid.
Covalent compounds have lower melting points compared to ionic compounds because covalent bonds are generally weaker than ionic bonds. In covalent compounds, individual molecules or atoms are held together by shared electrons, which are weaker than the electrostatic attraction in ionic compounds. Hence, less energy is required to break the bonds in covalent compounds, resulting in lower melting points.
Concrete is composed of both ionic and covalent compounds. The main components of concrete, such as Portland cement, consist of ionic compounds formed from calcium, silicon, and aluminum oxide. The aggregates used in concrete, such as sand and gravel, are composed of covalent compounds like silica and quartz.
PO4 is a radical, not a compound, and it has a covalent bond, not an ionic bond.
Ionic bonds are typically considered to be stronger, but sometimes compounds such as diamond are even stronger.
