Answer:
Explanation:
Speed of light = Wavelength x Frequency.
605 nm x Frequency = 3x10^8 m/s
6.05 x 10^-7 m x Frequency = 3x10^8 m/s
Frequency = 4.96 x 10^14 Hz
Answer:
Boron atoms lie in hexagonal aromatic graphite-like layers, with a charge of −1 on each boron atom. Magnesium (II) ions lie between layers Binary metal-boron compounds, the metal borides, contain boron in negative oxidation states. Illustrative is magnesium diboride (MgB 2).
