    Chemistry Understanding electronic configuration

    I don't really understand this electronic configuration of a thing. Suppose I want show the electronic configuration of calcium, how do I show it? Is like this 2, 8, 8, 2 or $$1s^22s^22p^63s^23p^64s^2$$

    Chemistry Understanding the concept of electron per shell

    Looking at Cacium for th electron arrangements according to shell numbers is 2, 8,8,2 since Cacium have four shells. Going by the formula 1st shell has:$$2n^2=2\times 1^2= 2 ~electrons $$ 2nd shell has:$$2n^2=2\times 2^2= 8 ~electrons $$ 3rd shell has:$$2n^2=2\times 3^2= 18 ~electrons $$ But...

    Calculating Radius & Water Depth of a Spherical Bowl

    The water level in a spherical bowl has a diameter of 30 cm. If the horizontal diameter of the bowl is 10 cm below the water level, calculate the radius of the bowl and the depth of the water in the bowl. I managed to draw a diagram below: In my drawing, I am seeing the sphere ABCD as the...

    Writing a logarithm in a form not involving logarithms

    I was not asked to find the value of x and y. I was only asked to write it in a form not involving logarithm. Is writing it in a form not involving logarithm the same as finding the value of x and y or solving the equation persay?

    Writing a logarithm in a form not involving logarithms

    logyx + logxy = 3/2 Solution $$\begin{align*}\log_{ y }{ x } + \log_{ x }{ y } &= \frac{ 3 }{ 2 } \\ \log_{ x }{ y } &= \frac{ \log_{ y }{ y } }{ \log_{ y }{ x } } \\ \log_{ y }{ x } + \frac{ 1 }{ \log_{ y }{ x } } &= \frac{ 3 }{ 2 } \\ \left(\log_{ y }{ x } \right)^ { 2 } + 1 &=...
