<span>Valence electrons are those in the outer most orbital shell (the valence shell). Elements in the same column (group) have the same number of valence electrons. Hydrogen is in Group 1. If you were to look at a periodic table of the elements, Lithium is right under Hydrogen.
You are correct, the answer is D. Lithium.</span>
From the atomic clock that utilizes C-133 which has an approximate frequency of 9.193 x 109 Hz. The wavelength of the energy is calculated to be 0.0326m.
From the given information:
- The frequency f = 9.193 × 10⁹ Hz = 9.193 × 10⁹ 1/s
- The wave speed c = 3.00 × 10⁸ m/s
Recall that:
The wavelength is the spatial successive distance between two crests of a wave and can be expressed by the formula:
Therefore, we can conclude that the wavelength of the atomic clock is 0.0326m. As such Option D is correct.

Answer: Iodine and Nitrogen
Explanation:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal.
Calcium (Ca) being a metal will donate electrons to form a cation called as . Thus it will bond ionically to non metals which can form anions.
Iodine can form and Nitrogen can form , thus forming and respectively.
