calcium chloride is an ionic compound. carbon dioxide is a covalent compound. which of these compounds.....?

Question

...which of these compounds forms as a result of the transfer of electrons from one atom to another??




EXPLAIN!!
D;
please please.

Answer 1

That would be your ionic compound. It's been a good while since high school chemistry, but from what I remember, an ionic compound forms from electron transfer...the calcium would give up electrons and in the process become a positive calcium ion, while the chlorine would capture an electron and become a negative chloride ion.
The carbon dioxide, on the other hand forms by covalent bonds, which means that the carbon and oxygen share electrons...to be more specific...the carbon has four electrons in its outer shell, and will share those electrons with two atoms of oxygen--two electrons for each oxygen atom. These two electrons will spend time orbittng both the carbon nucleus and the oxygen nucleus.

So, in a nutshell...an ionic bond is formed by the transfer of electrons from one atom to another, and covalent bonds are formed by the sharing of electrons between the atoms that make up that substancel

Answer 2

Calcium Chloride Compound

Answer 3

The ionic compound, calcium chloride.

Calcium atom, Ca, has 2 valence electrons and Chlorine atom, Cl, has 7 valence electrons.

To make any atom stable, usually, it must have 8 valence electrons except for Hydrogen, H and Helium, He, which only need 2 valence electrons to become stable.

Calcium will give its 2 electron to chlorine and becoming stable because the outer electron orbit was now empty. So the second outer orbit now is readily stable.

Chlorine however need 1 electron to make it stable. So 2 atom of Chlorine take 1 electron each.

The losing of electron make Calcium become + ion and receiving electron make Chlorine become - ion.

The different charge of the ion make it bond.

Answer 4

A covalent bond shares electrons. Carbon has four electrons on its outermost shell (valence electrons). Oxygen has six. They share the electrons.

An ionic bond actually transfers the electrons. This gives charges to polyatomic ions (ions always have charges).

If you need help counting electrons and figuring out the shells nad orbitals, I learned that fairly well. Feel free to contact me.
