Chlorine most strongly attracts extra electrons, while neon most weakly attracts an extra electron. At the boiling point the two phases of a substance, liquid and vapor, have identical free energies and therefore are equally likely to exist. Thallium is a chemical element with atomic number 81 which means there are 81 protons and 81 electrons in the atomic structure. Argon is the third noble gas, in period 8, and it makes up about 1% of the Earth's atmosphere. Palladium, platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Because of its closed-shell electron configuration, its density and melting and boiling points differ significantly from those of most other lanthanides. Tin is a post-transition metal in group 14 of the periodic table. Chemical Properties. The motion of individual atoms, ions, or molecules in a solid is restricted to vibrational motion about a fixed point. A possible crystal structure of Argon is face-centered cubic structure. Physical state : It refers to one of the three common states (gaseous, liquid and solid) of matter that exist at NTP (Normal Temperature and Pressure). Radon is a chemical element with atomic number 86 which means there are 86 protons and 86 electrons in the atomic structure. It is the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities. The chemical symbol for Gadolinium is Gd. Increasing the pressure on an material (especially for liquids or gases) decreases the volume of the object and thus increases its density via the atomic number density. Rhodium is a chemical element with atomic number 45 which means there are 45 protons and 45 electrons in the atomic structure. Argon has similar properties to Helium, Neon, Krypton, Xenon, and Radon. Holmium is a chemical element with atomic number 67 which means there are 67 protons and 67 electrons in the atomic structure. Its density is about 70% higher than that of lead, and slightly lower than that of gold or tungsten. This chemically inert element is colorless and odorless in both its liquid and gaseous forms. Although affinity varies greatly across the periodic table, some patterns emerge.

The chemical symbol for Boron is B. Carbon is the 15th most abundant element in the Earth’s crust, and the fourth most abundant element in the universe by mass after hydrogen, helium, and oxygen.

Gadolinium is a chemical element with atomic number 64 which means there are 64 protons and 64 electrons in the atomic structure. Iodine is the least abundant of the stable halogens, being the sixty-first most abundant element. Thorium is a naturally-occurring element and it is estimated to be about three times more abundant than uranium. Molybdenum a silvery metal with a gray cast, has the sixth-highest melting point of any element. Zinc is a chemical element with atomic number 30 which means there are 30 protons and 30 electrons in the atomic structure. Occurrence in Nature: The abundance of argon in the atmosphere is around 0.93 percent. Argon is a noble gas with the electronic configuration [Ne] 3{ s }^{ 2 } 3{ p }^{ 6 }. Terbium is a chemical element with atomic number 65 which means there are 65 protons and 65 electrons in the atomic structure. It is fairly soft and slowly tarnishes in air. The melting point of a substance is the temperature at which this phase change occurs.
