Answer:
Neon
Explanation:
1s² 2s² 2p⁶ 3s¹ or [Ne] 3s¹
The outer most shell is the 3s¹.
For this atom to achieve stability, if it loses the electron in the 3s shell, it would resemble an inert element with a complete octet configuration. Therefore, the atom would be like:
1s² 2s² 2p⁶ which is the configuration of Ne
Radio waves. A cell phone transmits its signal to the towers by <em>electromagnetic waves</em>.
The electromagnetic waves are in the <em>radiofrequency region</em> of the electromagnetic spectrum.
Most cell phones in North America use radiofrequencies between <em>700 MHz and 850 MHz</em> and between <em>1700 MHz and 2500 MHz</em>.
There are 9 H atoms in one molecule, so hydrogen is present in the greatest proportion by number of particles;
The ratio by particles is C:H:O:N = 8:9:2:1.
