What's the difference between ionic bond and molecular or covalent bond? pls be serious and help me understand​

It's all about understanding the concept, see my explanation.

Explanation:

A ionic bond is formed between a metal element and a non metal element always. On the other hand, a molecular bond or covalent bond is formed between 2 elements which are both non metals. A ionic bond is made when there is a electron transfer occurring meaning that one element is giving it's electron to another to ethier become a postive or negative ion. Whereas a molecular bond is made when two non metals elements share there electrons.

• An example of a ionic bond would be MgCl2 as we know magnesium is a metal and chlorine is a non metal.

• An example of a molecular bond would be NF

which we know are both non metals.

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
