We need to (i) find the volume of mercury; and (ii) convert this volume into a mass by use of the quoted . $"Volume of mercury"$ $=$ $76.0*cmxxpixx(0.5*cm)^2$ $=$ $59.7$...
It is a period or row that is energy level five or more, below calcium on . Two valence electrons places the element in the alkaline earth family or...
We are looking at the equation: $M(g) rarrM^+(g) + e^-$ Obviously you have to pump in energy. This energy INCREASES across a Period (from left to right) and DECREASES down...
Wavelength You use the Rydberg formula to calculate the wavelength, λ: $color(blue)(bar(ul(|color(white)(a/a) 1/λ = RZ^2(1/n_2^2 -1/n_1^2)color(white)(a/a)|)))" "$ where $R =$ the Rydberg constant ($1.097 × 10^7color(white)(l)...
The correct answer is d) B⁴⁺ has the lowest energy ground state. Bohr's equation is $E_n = -(Z^2R)/n^2$ For the ground state, $n = 1$, so $E_1 = -Z^2R$ If...
.........does it take you more energy to climb from the bottom of the stairs, than from 3 steps up the flight of stairs? Quite clearly it does. When...
We can immediately eliminate $Na$, $Z=11$, and $Co$, $Z=27$, because these give rise to an odd number of electrons in the ground state, the which must necessarily be UNPAIRED. As...
DISCLAIMER: Really long answer! The variational method states that from a guess wave function $phi$, we can approximate the ground-state energy for a system if we set $phi_0 =...
