with ur answers: thanks a lot! it's really helpful,but I just don't quite get this bit" As END increases, the ionic character increases." what are the ionic characters ? and do you mean the ionic character of the compound that's resulted?

[MarkRosengarten]

@mysstring1 Ionic character is the degree to which electrons are transferred from one atom to another. Nonpolar bonds have no ionic character as electrons are evenly shared between two atoms. As the END between bonded atoms increases, the electrons are increasingly drawn toward the more electronegative atom. This increases the ionic character. The point at which 50% ionic character is seen (END=1.7) and beyond is generally considered an ionic bond.

[MarkRosengarten]

@mysstring1 Ionic compounds dissociate (break up in water) and the ions so formed carry electrical charge, making the ionic solution an electrolyte. Strong acids dissociate into ions and conduct electricity, even though they are covalently bonded. Strong acids tend to be very polar and have higher ionic character than most molecules.

- I tried to find definitions for"electromagnetic attraction" but there wasn't one on the web, could you help me out ^^? in terms of atomic structure

[MarkRosengarten]

@mysstring1 Electrostatic attraction is the attraction of oppositely charged particles for each other. The stronger the attraction between the nucleus and the electrons, the radius will generally decrease.

[mysstring1]

just want to clarify, is it true that there are three types of chemical bonding?1.metallic bonding(occurs ONLY with two metals),2.ionic bonding(occurs ONLY with metal+ non metal) 3.covalent or molecular bonding( ONLY in non metal + non metal)? Are these just genralisations or it works for all?

- what is the difference between effective nuclear charge and nuclear charge? do those values determine the atomic radius of the elements?

[MarkRosengarten]

@mysstring1 These are generalizations geared to the high school level. There is a lot more to bonding than what you see in these videos, but these are the basics. You can have coordinate covalent bonding with a metal and nonmetals (as occurs in polyatomic ions). Nuclear charge is the charge of the nucleus, effective nuclear charge is the charge "felt" by electrons as their distance from the nucleus increases and the shielding effect of inner electrons diminishes the attraction.

see youtube can be helpful ^_^

wayyyyy better than my teacher!

[mysstring1]

thanks so much! your videos are brilliant !

Dude?. Dude. i bet im like the weirdo in some "pond" of smartee fisheees but, THANK THA LAWD! MAH BRUTHAH?. yu just helped a sister out yah heard?. speacially wiff dat test 2morrow :))) thank you for you are a good person

@mysstring1 Anything that has charge in motion conducts electricity. Metals allow electrons to flow freely from atom to atom. Ionic solutions contain mobile ions that can carry electrical charge. As END increases, the ionic character increases.
