Is it true or is it false Electronegativity increases continuously as atomic number increases?

False. Electronegativity does not increase continuously as atomic number increases. While there is a general trend of increasing electronegativity across a period from left to right on the periodic table, there are exceptions due to factors such as electron configuration and atomic structure.


Is americium electronegative?

All elements have some degree of electronegativity. Americium (Am) has electronegativity of 1.3


Is N-O ionic or covalent?

Definitely covalent. The electronegativity difference isn't great enough for a bond between Nitrogen and Oxygen to be ionic. In order for a bond to be Ionic, the electronegativity difference must be 2.7 or greater. The electronegativity difference of N and O is merely .4. Not even close! The further apart on the periodic table two elements are, the greater the electronegativity difference. Electronegativity GENERALLY increases going up and to the right on the table. There are, however, some cases in which exceptions can be noted, but they are not too common.

Which elements has least value for electro-negativity Lithium or Krypton?

Lithium has a lower electronegativity than krypton. The electronegativity for lithium is 0.98; the electronegativity for krypton is 3.0. Note that most noble gases in group 18 have no electronegativity at all since the do not make compounds. However, since krypton and xenon do make compounds under some circumstances, they do have a measurable electronegativity.


What are some exceptions to the octet rule?

No but apples do!


What happens when the nuclear charge increases across a period?

As the nuclear charge increases across a period, the number of protons in the nucleus increases. This leads to a stronger attraction between the nucleus and the electrons in the atom, resulting in a greater effective nuclear charge. This can lead to an increase in the atomic size and higher electronegativity across a period.
