These elements (neptunium and heavier) are called transuranic elements or trans-uranium elements. They could also properly be called artificial and radioactive.*Both plutonium and neptunium, first known through synthesis, have been found to occur naturally in trace amounts, along with americium, curium, berkelium and californium. These occur through a natural version of the synthesis process, within quantities of uranium ore.
A chemical symbol represents an element. For example, the chemical symbol H represents the element hydrogen.
a element b\c it has no other elements in the equation
In this case, the equation is balanced.
145/62 sm is the daughter element in the above equation.
Elements having more than 92 protons, the atomic number of uranium, are called transuranium elements.
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
These elements are not stable.

You probably are thinking of plutonium
The formula of which a compound is made of.Another OpinionA chemical equation represents how many atoms of each element are in one molecule of the substance, for example H2O has 2 Hydrogens and 1 Oxygen per water molecule.
In a chemical equation, each element has a symbol (in the periodic table in the elements). You use those symbols to create a chemical equation. For example, water is H2O. "H" represents Hydrogen, "O" represents Oxygen and the 2 means that there are two oxygen particles for each oxygen particle. Together, this creates one water molecule.

CaO + H2O -> Ca(OH)2 If you are in doubt about this then count the number of atoms of each element on each side of the equation to verify that they correspond.
n ∑(f(x)/n) x = 0 Where f(x) represents the xth element in the set you're averaging, and n represents the number of elements in that set.
