There are 3 main types of chemical bonds: covalent, ionic, and metallic.
False
True
Covalent bonds occur when electrons are shared between 2 atoms and the bond is classified as polar or nonpolar.
Ionic bonds occur when one atom gives up one or more electrons and another atom accepts the electron.
Metallic bonds occur between 2 metal atoms of the same or different elements.
What are covalent bonds?
What are ionic bonds?
What are metallic bonds?
pick 2
is the way that metal atoms are kept together within a metal material. A metallic bond is a type of chemical bond similar to a covalent bond. Atoms in metals are held together by forces caused by the valence electrons
A polar covalent bond usually involves 2 different types of atoms and occurs when one atom has a stronger pull on the electron, or a greater electronegativity. The (a) atom will have a slightly (b) charge and the other atom(s) will be slightly positive which results in poles on the molecule.
What is the difference in nonpolar and polar covalent bonds?
Pauling Units (PU) are used to measure the (a) of a (b) .
Polar bonds have a measurement of 0.5-1.9 PU.
Non-polar bonds have a measurement of <0.5PU.
So polar non-polar has less than 0.5PU.
Ionic bonds occur when one atom (a) or more electrons and another atom (b) the electron. (c) ions attract each other resulting in a bond. The positively charged atom is called a cation and is usually a metal. The negatively charged atom is an anion and is usually a non-metal.
Ionic bonds are giving to each other. Here. Have this electron. The other said thank you. I'll accept it. One of the electrons being shared by the ionic bond is the positive
The positive atom will have more protons than electrons
Which is the Positive atom?
anion and usually is a metal
anion and usually is a non-metal
cation and usually is a metal
cation and usually is a non-metal
If an atom has more electrons than protons, it is negative This is
anion and usually is a metal
anion and usually is a non-metal
cation and usually is a metal
cation and usually is a non-metal
So Ionic is sharing of atoms. One might be a positive cation atom. It will have more protons than electrons. It is usually a

So Ionic is sharing of atoms. One might be a positive cation atom. It will have more protons than electrons. It is usually a metal. The anion, the non metal one, will have more electrons than protons meaning it is negatively charged atom.

true I guess
non metal

If an atom loses an electron it lost a negative. So it should become
If an atom gains an electron it gained a negative. So it should become
Covalent shares so their outer cloud both might touch or connect like this picture where the ionic are crossing over to the other. The covalent sharing it at the same time. Both won't let go. It is sharing between non metal and
nonmetal or metalloid
Metallic of between metals of course. They seem to be a big brotherhood that of electrons joining together, The metallic atoms all lose their electrons and they are now all packed together. The atom is now positively charged bc they lost the electrons. The electrons all left and join together. Left their master atom. But the master happy if it likes being positive.
described as sea of electrons
occur between 2 metal atoms of the same or different elements. The metals give up electrons which causes them to have a positive charge. The electrons hover near the metals and are all attracted to the same area, which basically bonds them together. These floating electrons are what allows metals to conduct electricity well and be malleable.
