A. for main-group elements, electron affinity generally becomes more negative as you move to the right across a row
B. for main-group elements, electron affinity generally becomes more positive as you move to the right across a row
C. there is not a corresponding trend in electron affinity...
True or false statements.
1. Within a family, elements with higher atomic numbers pull less strongly on electrons in a bond because the atoms have lower effective nuclear charge.
2. Within a family, elements with higher atomic numbers have lower ionization energy because the atoms have lower...
pls help me with these questions, i dont get them its confusing please answer + explain throughly!!! thanks so much!
1. ELEMENTS: B, Al, Ga, IN
*List them in order from small to large
*Would they gain or lose e- to form ions?
-What charge would the ion have?
*Would these be considered cations or...

For eg, atomic radius decreases from left to right across a period. Yet Oxygen has a larger radius than Nitrogen.
I want to know all the other exceptions along with their reasons. Please help!
Thanks.
37.Which of the following best explains the periodic trend of atomic radius:
a) the balance of positive and negative charges
b) radius decreases from left to right and bottom too top
c) the positive nuclear charge increases within a period without an increase energy level
d) the opposites...

can you tell me how periodic properties like ionization enthalpy and electron gain enthalpy vary in periodic table THROUGH BOHR'S THEORY (AND EQUATIONS)??
Plz help, i need this by 3 days.

atomic radius,ionization energy, electron affinity,
for example i have a lot of question that ask place the elements in increasing __(one of those above)
or which one has the highest atomic radius or what not
ex. Li,K,C,N ,place atoms in order from increasing ionization energy
would it be...
Why is the reaction of sodium with water more violent than that of calcium and water??
And why is fluorine so extremely reactive? (in terms of atomic radii and nuclear charge)
Please help!!
THANK YOU!!
A normal healthy heart beats at a variable rate with extraordinarily complex fluctuations across a wide range of time scales. Reduced complexity of heart rate has both clinical and dynamical significance - it may provide warning of impending illness, or clues about the dynamics of the heart's...
Welcome, ununseptium. With 117 protons, it is the latest super-heavy element, a discovery that fills a gap in the current periodic table of elements, and bolsters the idea that we may yet find an "island of stability" among heavyweight atoms More »
