Ptable is a great website that shows you a dynamic periodic table. It can show you which elements are Halogens, Alkali metals, transition metals, noble gases, and etc!
Chemicalaid is a nice website to find out more information about specific elements, it also lists every element on the periodic table.

Answer:If you are sedentary (little or no exercise) : Calorie-Calculation = BMR x 1.2.
If you are lightly active (light exercise/sports 1-3 days/week) : Calorie-Calculation = BMR x 1.375.

Answer:
Does the wave require a medium in order to travel?
Explanation:
The question whose answer would determine whether the wave in question is mechanical or electromagnetic would be <u>if the wave requires a medium in order to travel or otherwise.</u>
<em>A mechanical wave would require a medium in order to transport its energy from one place to another, that is, travel. On the other hand, an electromagnetic wave does not require any medium in order to travel, that is, it can travel through vacuums or empty spaces</em>. <u>Light</u> and <u>sound waves</u> are typical examples of <u>electromagnetic</u> and <u>mechanical waves</u> respectively.
<span>I think that the effective nuclear charge increases as you go up a group and across a period.
so maybe Rh, K, Ti, Mg, P
I hope I helped :)</span>
