Phosphorus is a chemical element; it has symbol P and atomic number 15. Elemental phosphorus exists in two major forms, white phosphorus and red phosphorus, but because it is highly reactive, phosphorus is never found as a free element on Earth.
May 22, 2017 · Determine the mass of phosphorous from the periodic table. Because the atomic mass of phosphorous is 30.97 amu, we can say the mass is. m = 4 ×30.97 = 123.88 g mol. This means that 1 mol of P4 weighs 123.88 grams.

Phosphorus is a chemical element with atomic number 15 which means there are 15 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. The total number ...
Atomic mass of Phosphorus is 30.9738 u. The atomic mass is the mass of an atom. The atomic mass or relative isotopic mass refers to the mass of a single particle, and therefore is tied to a certain specific isotope of an element. The atomic mass is carried by the atomic nucleus, which occupies only about 10-12 of the total volume of the atom or les...
The atomic radius of Phosphorus atom is107pm(covalent radius). It must be noted, atoms lack a well-defined outer boundary. The atomic radius of a chemical element is a measure of the distance out to which the electron cloud extends from the nucleus. However, this assumes the atom to exhibit a spherical shape, which is only obeyed for atoms in vacuu...
The number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Phosphorus is 15.Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom. Since the number of elect...
Density of Phosphorus is 1.823g/cm3. Typical densities of various substances are at atmospheric pressure. Density is defined as the mass per unit volume. It is an intensive property, which is mathematically defined as mass divided by volume: ρ = m/V
Electron affinity of Phosphorus is 72 kJ/mol. In chemistry and atomic physics, the electron affinityof 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. X + e– → X–+ energy Affinity = – ∆H In other words, it can be e...
Electronegativity of Phosphorus is 2.19. Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom to attract electrons towards this atom. For this purposes, a dimensionless quantity the Pauling scale, symbol χ, is the most commonly used. The electronegativity of Phosphorus is: χ = 2.19
First Ionization Energy of Phosphorus is 10.4867 eV. Ionization energy, also calledionization potential, is the energy necessary toremove an electronfrom the neutral atom. X + energy → X+ + e− where X is any atom or molecule capable of being ionized, X+ is that atom or molecule with an electron removed (positive ion), and e−is the removed electron....
