Properties of Gamma rays?
Hel

Some of the properties are:

1. Gamma, γ-rays are not deflected by electric and magnetic fields. It shows that they do not have any charge.

2. Gamma, γ-rays are electromagnetic waves like X-rays. The wavelength of γ-ray photon is smaller than that of X-rays.

3. The rest mass of a Gamma, γ-ray photon is zero. (Photon has mass zero but it has momentum, why?)

4. Gamma, γ-rays travel with the speed of light.

5. Gamma, γ-rays have very large penetrating power. They can pass through several centimeter of iron and lead.

6. Gamma, γ-rays can produce fluorescene in a substance like willimite.

tracks, burrows, eggshells, nests, tooth marks, or gastroliths

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
