What is the trend for electron affinity?
As you go across a period; Left to right, the electron affinity increases. As you go down a group; top to bottom, the electron...
What is the general trend of electron affinity as you go left to right across the periodic table?
Generally, it gets stronger.Elements like to have a full outer orbit. They have to fill up their inner orbits before they fill up...

Does electron affinity gain electrons?
Yes. Electron affinity is the process by which a neutral atom gains an electron and the EA is the measure of energy released. The...
How does the periodic trend of atomic radius relate to the addition of electrons?
because they both react in different ways and otherwise known as chemical reactions. the atomic radius is the center of the atom...

What is the trend in electron affinity of elements within a group?
decreases from top to bottom
What is the trend in the electron affinity of the elements across a period?
Generally electron affinity goes up as you go from left to right across the periodic table, and decreases as you go down a...

Why is the electron affinity of nitrogen lower than the electron affinity of carbon?
I believe it is because of the 1/2 filled p subshell. In N, the p subshell is half filled. Thus, it is happy where it is and it...

What is the Electron affinity for Na?
electron affinity of Na is negative
What periodic trends exist for electrongavity?
Electronegativity increases from left to right across a period from column 1 through column 17 but drops sharply from column 17...
In: Chemistry | Periodic Table
Why does electron affinity decrease?
It decreases as you go down a group because the atomic radius increases, and the energy shells increase, so the attraction is...
In: Chemistry
Why is beryllium's electron affinity negative?
It is NOT negative (for the first IE). Because Be's configuration is 1s2 2s2, we observe that it has no vacant orbital to...

Is specific heat a periodic trend?
There is no specific heat trend on the periodic table because the gases on the periodic table are solids, liquids, and gases, and...
What does high electron affinity mean?
electron = electron Affinity = Desire hence - high electron affinity is a molecule or ion that will draw electron to itslef and...

What is the periodic trend for electrongativity?
Electronegativity increases when going right along a period and decreases when going downwards along a group.
In: Chemistry | Periodic Table
The electron number is where on a periodic table?
The atomic number is the number of protons in the nucleus of any atom of any element. Because all atoms are neutral, the number...
