These nuclides are generally referred to as naturally occurring radioactivity and are derived from the radioactive decay of thorium and uranium.

Cosmogenic nuclides are atoms that are constantly being synthesized from the bombardment of planetary surfaces by cosmic particles (primarily protons ejected from the Sun), and are also considered natural in their origin.

You put on a false smile for everyone else and grin and bear it, but with him, you are happy to let your true emotions show. You share a mutual respect You respect and love each other for who you both are.

Even his bad traits are loveable and neither of you want to change a single thing about the other. You can talk till the sun comes up You’re so engrossed in each other, that you don’t even notice what the time is.

We’re all looking for the perfect relationship but is there such a thing and can we realistically have it all?In the everyday world around us, we observe three very different types of materials: gases, liquids, and solids.Closer examination of the physical properties of homogeneous crystalline solids shows that they can be subdivided into four distinct categories according to their physical properties and the different forces holding them together.The positive nuclei of the atoms are embedded in the sea as a close-packed three-dimensional array. The electrons are constrained about each atom, some atoms with excess positive charge (cations) and some with excess negative charge (anions).The ions are packed closely together, held by coulomb (electrostatic) forces of attraction. A solid that is extremely hard, that has a very high melting point, and that will not conduct electricity either as a solid or when molten is held together by a continuous three-dimensional network of covalent bonds.
