Answer:
Ionic bonds are opposite, whereas Covalent bonds are opposite.
Explanation:
Two opposite ions attract each other and form the ionic bond. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and othercovalent bonds.
Examples:
Sodium Chloride and Sodium Fluoride are examples of <em>Ionic</em><em> </em><em>bonds</em><em>.</em>
<u>and</u>
Water and Carbon Dioxide are examples of <em>Covalent</em><em> </em><em>bonds</em><em>.</em><em> </em>
Answer:
MgO has a highest melting point
C5Br has lowesst
Explanation:
It takes a lot of energy to overcome the strong electrostatic forces of attraction between oppositely charged ions, so ionic compounds have high melting and boiling points. ... Magnesium oxide is made from ions with two charges (Mg 2+ and O 2-) and so has a much higher melting point of 2852°C.
A halogen is example of
nonmetal. The answer is letter A. When compounds containing halogens they are
called salts thus the name “salt – former”. Halogen consists of Fluorine,
Chlorine, Bromine, Iodine, Astatine.
If a lone pair is participating in resonance, this capability the atom is both Sp2 or Sp hybridized. Looking at the Sp2 case, that ability there are 3 Sp2 orbitals and one P orbital. Assuming there is no formal cost on the atom, the three hybrid orbitals are used for bonding and the lone P-orbital holds the lone pair. Sp3 orbitals are no longer involved with resonance so the lone pair worried in resonance should never be in an Sp3 orbital.
A mathematically described area round a nucleus in an atom or molecule that may also include zero, one, or two electrons Electrons organize themselves in cloudlike areas round the nucleus referred to as orbitals.
