How do the chemical characteristics of the elements in a period change from left to right across the periodic?

Question

table?

Answer 1

From left to right, the only generalizations are increasing electronegativity and valence shell filling. With the inert gases, you can't say, however, that they are more electronegative, since they have the neutral full valence shell.

BTW: coool name there, lithiumdeuteride. I suppose that would be lithium-6 deuteride!

Answer 2

In general, the elements on the left side tend to form positive ions, while the elements on the right side tend to form negative ions. That is quite an oversimplification, though.

The real story has to do with valence shell structure, electronegativity, and atomic size, but it gets quite complicated.

Answer 3

As a bio-chem undergrad. i discover that i did no longer memorize the 1st 2 rows the table on purpose. Memorization of the 1st 2 rows come from doing homework issues repeatedly back. via the time you get via introductory and prevalent chemistry, you will a minimum of recognize the atomic variety and mass of H, N, C, and O interior the back of your head. in all possibility even some different components including Cl, Fl, B, S, I, Na, Li, Fe..and so on.. yet a number of my instructors has reported, different than for some ordinarily used components, something of the periodic table would want for use as approaches, no longer memorized.
