(1x5) marks Iron is an important element, which our body needs for many of its functions. In our blood, it is the carrier of Oxygen. It is the fourth most common element in the earth's crust. In today's world, iron and its alloys are the most common industrial material due to its low cost and better mechanical properties. The extraction of iron metal takes place from its ore in a number of steps, which are summarized below. Iron ore, coke...

From the information below, identify element X. a. The wavelength of the radio waves sent by an FM station broadcasting at 97.1 MHz is 30.0 million (3.00×107) times greater than the wavelength corresponding to the energy difference between a particular excited state of the hydrogen atom and the ground state. b. Let V represent the principal quantum number for the valence shell of element X. If an electron in the hydrogen atom falls from shell V to the inner shell...
