C. MgCl2
This structure forms a ionic bond, which are generally stronger than covalent bonds. All of the other choices are covalent.
Answer:
+1
Explanation:
A Potassium atom is represented with the sign "K" in chemistry and have atomic number 19.
The charge of electrons causes a matter to experience a force and it can be positive or negative.
In Potassium atom, the electric charge is +1 to enter a stable electron configuration as there is only one valence electron in the outermost shell of potassium atom. As potassium atom will lose electron it will become positively charged.
Hence, the correct answer is "+1".
Answer:
Well they both would say numbers
Explanation:
The reason why is they both speak english
There would be no nobr and it would just be 2
An ionic bond is formed by the transfer of electrons from one atom to the other. It is usually formed between a metal + non-metal.
A covalent bond is formed by sharing of electrons between two atoms. It is formed between two nonmetals. A polar covalent bond is formed between 2 non-metals which differ in their electronegativities. In contrast, in a non-polar covalent interaction the two atoms could either be the same or have very close electronegativities.
1) P and I : Both non-metals with different electronegativities= Polar Covalent
2) Fe and O: Metal + non-metal = Ionic
3) S and Cl: Both non-metals with different electronegativities= Polar Covalent
4) S and S: Both non-metals and the same atoms = Non-polar Covalent
5) Br and Br: Both non-metals and the same atoms = Non-polar Covalent
6) O and Cl: Both non-metals with different electronegativities= Polar Covalent
7) Be and Cl: Metal + non-metal = Ionic
8) Al and N: Metal + non-metal = Ionic
