What properties and special abilities does californium have?
Physical properties of californium - Atomic number: 98 - Isotopes: 20 - Isomers: 1 - Electron configuration: [Rn]5f10.7s2 - Electrons per shell: 2, 8, 18, 32, 28, 8, 2 - Thermal conductivity: - Electrical resistivity: - Mohs hardness: 3-4 - Californium is malleable - Californium is paramagnetic at room temperature - Melting point: 900 0C - Boiling point (estimated): 1 470 0C - Density: 15,1 g/cm3 - First ionization energy: 608 kJ/mol - Crystalline structure (at r.m.): double hexagonal close-packed - Bulk modulus: 50 ± 5 GPa *Californium applications - neutron source to start-up nuclear reactors (Cf-252) - neutron source for neutron diffraction instruments (Cf-252) - neutron source for neutron spectroscopy instruments (Cf-252) - raw material for the preparation of heavier chemical elements (Cf-249) - source for portable neutron activation instruments (Cf-252) - source for radiation therapy with neutrons (Cf-252) - source for neutron radiography (Cf-252) - source for moisture detectors (Cf-252) - source for gold and silver detectors (Cf-252) - source for analysis instruments of coals, cements etc. (Cf-252)
What family are lithium in?
Lithium is the smallest(first) member of Group 1 , the Alkali metals.
Was polonium the first source of radioactivity?
All isotopes of polonium (all 25 of them) are radioactive. Only traces of a single isotope exist in nature.
What was the element Krypton first used for?
Krypton was first used as a light source since it has several emission lines that make the ionized krypton gas release appear whitish. It was used in some photographic flashes used in high speed photography and when mixed with another element by the name of 'argon' it was used as flourescent bulbs.
How many protons does an atom of the first element listed on the periodic table have?
Hydrogen, being the first element, has one proton and one neutron in its nucleus.
What is the first element after hydrogen that which has a neutron?
Helium. All elements have neutrons except hydrogen.
What is the first member of the noble gases and the second most abundent element in the universe?
Helium is the first member and the most abundent element in the known universe
What element is the first member of the rare earth metals?
Be; Beryllium Element #4
What element is the first member of the alkaline earth metal?
Alkaline earth metals are in the second group. Be is the first metal of them.
What element was created by the first H bomb test?
Element number 99, later named Einsteinium, was discovered in the debris from the first hydrogen bomb explosion in 1952. Only a tiny number of atoms were detected, formed from the decay of neutron-bombarded californium nuclei.

Is it true that MLA citations always begin with the title of the source?
No, MLA citations typically begin with the author's name for most sources. If there is no author, then the title of the source is used as the first element in the citation.
