In nuclear industry gadolinium is commonly used as a neutron absorber due to very high neutron absorbtion cross-section of two isotopes 155Gd and 157Gd. 7 protons 7 neutrons 7 electrons. Elemental rubidium is highly reactive, with properties similar to those of other alkali metals, including rapid oxidation in air. Protons and neutrons are found in the nucleus, so the number of neutrons is found by subtracting the proton number from the mass number I.e. The chemical symbol for Mendelevium is Md. These have similar chemical properties, but palladium has the lowest melting point and is the least dense of them. 8 B. In nuclear industry boron is commonly used as a neutron absorber due to the high neutron cross-section of isotope 10B. Beryllium is a hard, grayish metal naturally found in mineral rocks, coal, soil, and volcanic dust. Tungsten is an intrinsically brittle and hard material, making it difficult to work. Lead is soft and malleable, and has a relatively low melting point.
