All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions. Gold, for instance, is an element, and so is carbon. There are 118 elements, but only 92 occur naturally.

Nonmetals rarely lose electrons in chemical reactions because?
ziro4ka [17]
The reason for this is because nonmetals, have close to fulfilling an octet and need to gain few more electrons to do this, not to lose more. Nonmetals, because of the fact they need only few more electrons to satisfy their octet they would receive or share electrons to do this.

The property that nonmetals have are that they are very electronegative, they possess a strong affinity to pull electron density closer, because they possess fewer electron shells and possess even protons this allows for this.

Green plants absorb sunlight to power photosynthesis, the chemical synthesis of food from water and carbon dioxide. The compound
tekilochka [14]

Answer: The frequency of this light is 6.74\times 10^{17}Hz.

Explanation:-

To calculate the frequency of light, we use the equation:

\lambda=\frac{c}{\nu}

where,

\lambda = wavelength of the light  =430nm=430\times 10^{-9}m      1nm=10^{-9}m

c = speed of light = 2.9\times 10^8m/s

\nu = frequency of light = ?

\nu=\frac{c}{\lambda}

\nu=\frac{2.9\times 10^8m/s}{430\times 10^{-9}m}

\nu=\frac{2.9\times 10^8m/s}{430\times 10^{-9}m}=6.74\times 10^{17}s^{-1}=6.74\times 10^{17}Hz

The frequency of this light is 6.74\times 10^{17}Hz.
