The first ionisation energy of silicon is greater than that of phosphorus.
Sodium would form Na+
Oxygen would form O-2
Phosphorus would form -3 or +5
Sodium and oxygen would combine to form ionic bonds because one is a metal and the other is non-metal, while Phosporus and oxygen would combine to form covalent bonds because they are both non-metals.
Answer:
linear angleee
Explanation:
lol i dont know what to put here
In an equation, 40kJ + 2SO₃ (g) -->2SO₂(g) + O₂(g), if pressure added, the equilibrium shifts to the left side of the reaction because it has fewer moles of gas.
<h3>What is Le Ch atelier's principle?</h3>
Le Ch atelier's principle states that if the pressure is added in a nay reaction, then the equilibrium will be shifted toward the side where there are fewer atoms.
In this case, there are fewer moles on the left side.
Thus, when pressure is added, the equilibrium shift to the left side due to Le Ch atelier's principle.

Answer: An ionic bond is a bond that forms between ions with opposite charges.
Explanation:
A chemical bond formed by the transfer of electrons from one atom to another is called an ionic bond.
For example, sodium has electronic distribution as 2, 8, 1 and chlorine has electronic distribution as 2, 8, 7.
In order to attain stability, sodium needs to lose 1 electron and chlorine needs to gain one electron. Therefore, sodium will transfer its one valence electron (forming 
ion) to chlorine atom (forming 
ion) which leads to the formation of NaCl compound.
Thus, we can conclude that an ionic bond is a bond that forms between ions with opposite charges.
