What element is in Group 8 Period 1?
Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.
In which period can you find the element iron?
period 4
The period 4 transition metals are scandium (Sc), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), and zinc (Zn).
What element is in group 12 Period 7?
Zinc group element, any of the four chemical elements that constitute Group 12 (IIb) of the periodic table—namely, zinc (Zn), cadmium (Cd), mercury (Hg), and copernicium (Cn).
What elements is in period 4 Group 8?
Iron (Fe) is an element in group 8. Iron is the most common on Earth among elements of the period, and probably the most well-known of them. It is the principal component of steel.
What is the atomic number of fluorine on the periodic table?
Fluorine – Periodic Table Element Fluorine Atomic Number 9 Symbol F Element Category Halogen Phase at STP Gas
Are there any elements that are similar to fluorine?
Fluorine (F), chlorine (Cl), bromine (Br), and iodine (I) also exhibit similar properties to each other, but these properties are drastically different from those of any of the elements above.
How is the element fluorine classified as a halogen?
The chemical element fluorine is classed as a halogen and a nonmetal . It was discovered in 1813 by Humphrey Davy. The fluoride ion, from the element fluorine, inhibits tooth decay. Fluorite (originally called fluorspar) crystals in daylight. The same fluorite crystals fluorescing in darkness after exposure to light.
How is the electron affinity of fluorine determined?
Electron affinity of Fluorine is 328 kJ/mol. In chemistry and atomic physics, the electron affinity of an atom or molecule is defined as: the change in energy (in kJ/mole) of a neutral atom or molecule (in the gaseous phase) when an electron is added to the atom to form a negative ion.
