Need Answer! :(
D) Are always two metals.
a) is for ionic compounds
b) is for nonpolar covalent bonds
c) same as nonpolar covalent bonds
b) Must be of different elements:)

∙ 13y agoCovalent bonds are formed between two non-metals. For example, CH4, commonly known as methane, is a covalent compound. These compounds are formed by sharing of valence electrons. Covalent compounds formed by carbon and hydrogen only are called hydrocarbons.

∙ 15y agoA polar covalent bond is created when one atom in a bond is more electronegative than the other. What this means is that the electrons from that bond have a greater draw to the more electronegative atom than the other. Since electrons tend to move around quite a bit within the molecular orbitals that are formed between two atoms, what is happening to the electrons is that over time they are spending more time on the electronegative atom than on the less electronegative atom.

∙ 14y agoPolar bonds are bonds between atoms that have a difference in electornegativities. the more electronegative atom pulls the electrons closer to itself making it semi positive while the other atom in the bond becomes semi neg. one might ask why does the more electronegative atom just take the electron, the answer is because the two atoms share the electrons to fill there outer shell (octet rule). bonds weather polar or not are formed in order to lower energy states and make the atom more stable.

∙ 11y agoIf you consider the covalent bond to be an electron cloud sitting between two atoms in a polar bond the electron cloud is closer to the more electronegative element.

What happens to valence electrons in non-polar covalent bonds compared to polar covalent bonds?
The electrons are equally shared in a non-polar bond and uneqaully (spending more time near the more electronegative atom) in a polar covalent bond
What type of bond shares valence electrons?
A covalent bond (non-polar and polar)
What happens with electrons in a non polar covalent bond?
Electrons are shared equally by two atoms.
What do metals do with their valence electrons when they form chemical bonds?
Metals generally transfer their electrons, in other words are oxidised to form cations, such as Na+ and Fe3+ In a metallic bond the valence electrons are delocalised around the lattice (in the solid) or the metal atoms in molten state (sea of electrons model) Metal atoms can also form covalent bonds, these are most common amongst the more electronegative metals, in these, as in any other covalent bond the electrons are shared (generally in a polar covalent bond)
If atoms that share electrons have an unequal attraction for the electrons the bond is called?
i was doing my chemistry hw, and found this. I hope that it helps you too: polar covalent

What type of bond shares valence electrons?
A covalent bond (non-polar and polar)
What is a covalent bond called when the outer valence electrons are positioned unequally?
A Polar Covalent bond.
What is the name of the chemical bond that has uneven sharing of valence electrons?
Polar covalent bond
What is a molecule that the valence electrons are shared equally between the two atoms?
a non polar covalent molecule
What happens with electrons in a non polar covalent bond?
Electrons are shared equally by two atoms.
What happens between atoms in covalent and polar covalent compounds?
electrons are exchanged... ur welcome lol ;-)
Equal shared attraction between valence electrons results in what kind of bond?
A non-polar covalent bond.
What do electrons do for polar covalent?
When the difference of the electronegativities of the atoms is significanct the bond is covalent polar. The electrons are of course shared.
Covalent bond in which electrons are shared equally?
A non-polar covalent is one in which the electrons are shared equally.
