An atomic mass unit ( amu) is defined as one-twelfth of the mass of a carbon-12 atom. Three neutron sources ( 3, 4, 5), using lowenergy protons and lithium target, provide neutron flux with a narrower energy distribution and a smaller contribution of thermal and fast neutrons, which is important for the quality of therapy. Atomic nuclei consist of protons and neutrons, which attract each other throughthe nuclear force, while protons repel each other viathe electric forcedue to their positive charge. .ec_show_two_column_only{ display:none !important; } .ec_product_type3 .ec_product_addtocart:hover{ background-color:#666666 !important; } Atomic number of the element =. .ec_product_li:nth-child( 2n+1 ){ clear:both; } And since it has 54 neutrons, that makes it Zr-94^2+ ion. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. In example B, it could be labeled with a noble-gas core of electrons.
