The outer electron is further from the nucleus of the atom, therefore feeling less effective nuclear attraction .
As you descend the group 1 metals, more shells of electrons are present in the metal...

Rearrange the second equation in the form y = mx + c to get y = 3x + 4. Divide the first equation by 2 to get y = 2x + 1. When the lines intersect, they'll have the same x and y values, hence, set the equ...

In physics questions it is useful to not plug numbers in until the end and instead work through algebraically. Let's say the angle of elevation is a, the mass is m, the velocity at the end of the plank is...

The derivative of the function where x=π/6 is defined asThe limit as h->0 of [sin(h+π/6)-sin(π/6)]/hUsing the double angle formula, sin(h+π/6) = sin(h)cos(π/6) + cos(h)sin(π/6) = √3sin(h)/2 + cos(h)si...

President Roosevelt first faced criticism of the New Deal from the Supreme Court, which ruled that some of the measures of the New Deal were unconstitutional. They argued that the New Deal gave the federa...
