Is sodium and magnesium an ionic compound?
There is a strong electrostatic force of attraction between these oppositely charged ions – this is called an ionic bond. The slideshow shows ionic bonds being formed in sodium chloride, magnesium oxide and calcium chloride.
How do you combine ionic charges?
To find the formula of an ionic compound, first identify the cation and write down its symbol and charge. Then, identify the anion and write down its symbol and charge. Finally, combine the two ions to form an electrically neutral compound.
How will two anions react if they come near each other?
These oppositely charged ions attract each other to form ionic networks (or lattices). Electrostatics explains why this happens: opposite charges attract and like charges repel. When many ions attract each other, they form large, ordered, crystal lattices in which each ion is surrounded by ions of the opposite charge.

What is the correct name for the ionic compound AgBr?
bromine. Silver bromide (AgBr), an important component of photographic film, is, like silver chloride and iodide, light sensitive.
Which is the strongest Lewis acid?
This bond decreases the boron atom’s electron deficiency, and its Lewis acid character diminishes. The bonding tendency in BF3is optimum and decreases from BF3to BI3. Thus BI3behaves as a Lewis acid which is strongest. Therefore, option D is the right answer.
Is AlCl3 a strong Lewis acid?
“Exemplary” Lewis acid AlCl3 is not a strong Lewis acid in the solid state! Thus, it resembles R- and β-AlF3 as proven by catalytic experiments. Responsible are halogen atoms forming the outer surface and covering the aluminum sites as shown by surface energy calculations.
Does AlCl3 octet?
In some of its compounds, aluminum violates the octet rule by having only six valence electrons. For example, aluminum chloride, AlCl₃, has only six valence electrons around the Al atom. In this structure, both Al atoms do satisfy the octet rule.
Why is AlCl3 incomplete octet?
AlCl3 is an exception to octet rule as it is an electron deficient compound and its octet is incomplete due to which it dimerises as AlCl , to get stability.
Why does AlCl3 disobey the octet rule?
AlCl3, if we draw the covalent structure of AlCl3, Al has 6 valence electron and NOT 8 valence electron so it lacks electrons and it is an electron-deficient compound so it is not able to follow the octet rule.
Why pcl5 and BF3 are violation of octet rule?
Boron has 6 electrons around it. Thus octet rule is violated. BF3 neutralises deficiency when reacts with a compound having lone pair of electrons such as NH3. It forms cordinate bond with ammonia by accepting the lone pair of electrons of nitrogen atom.
