Is this compound ionic or covalent? Lead and Oxygen: Lead is a metal that belongs to the carbon family of the periodic table. The chemical symbol for lead is Pb. And oxygen is a non-metal that belongs to the oxygen family of the periodic table. The chemical symbol for o...
Is this compound molecular or ionic? What is the formula and name of the ionic compound that contains NH4 as the cation and C2 O4 with a plus 2 charge as the anion? What is the name of the compound Al(OH)3? Is it ionic or covalent?
Normally, if the difference in electronegativity is larger than 1.7, then it is more ionic than covalent; equals 1.7, 50% covalent 50% ionic; smaller than 1.7, more covalent than ionic. Thus, you can also use this as a guideline to judge whether a binary compound (like NaCl) is ionic...
Is NaCl an ionic salt? Sodium chloride , commonly known as salt (although sea salt also contains other chemical salts), is anionic compoundwith the chemical formula NaCl, representing a 1:1 ratio of sodium and chloride ions. ... In its edible form of table salt, it is commonly used as...
When two atoms combine, they form a compound or molecule in a chemical bond, which links them together. This bond can be ionic or covalent. In an ionic bond, one atom donates an electron to the other to stabilize it. In a covalent bond, the atoms are shared by the electrons. ...
Is metallic bonding covalent or ionic?Metallic BondingMetallic bonding is utilized to express the features of metals. This is because the metallic bonds contain strong atomic attraction that enables the electrons to transport electricity and other forms of energy across the metals. Also, metallic ...
