What is the electronic configuration of Calcium 20? What is the boiling Point of Calcium in Kelvin?īoiling Point of Calcium in Kelvin is 1757 K. Melting Point of Calcium in Kelvin is 1115 K. What is the melting Point of Calcium in Kelvin? What is the boiling Point of Calcium?īoiling Point of Calcium is 1757 K. Calcium has 20 electrons out of which 2 valence electrons are present in the 4s2 outer orbitals of atom. How many valence electrons does a Calcium atom have?Ĭalcium has 2 valence electrons. What is the color of Calcium?Ĭalcium is of Silver color. It is located in group 2 and period 4 in the modern periodic table. Calcium is the 20 element on the periodic table. What is the position of Calcium in the Periodic Table?Ĭalcium is a chemical element with the symbol Ca and atomic number 20. Calcium is a chemical element with symbol Ca and atomic number 20. To form abbreviated notation of electronic configuration, the completely filled subshells are replaced by the noble gas of the preceding period in square brackets. The abbreviated electronic configuration of Calcium is 4s2. What is the abbreviated electronic configuration of Calcium? The electronic configuration of Calcium is 1s2 2s2 2p6 3s2 3p6 4s2. What is the electronic configuration of Calcium? Optical Properties of Calcium Refractive IndexĪcoustic Properties of Calcium Speed of SoundĬalcium Thermal Properties - Enthalpies and thermodynamics Refer to table below for the Electrical properties ofCalcium Electrical ConductivityĬalcium Heat and Conduction Properties Thermal ConductivityĬalcium Magnetic Properties Magnetic Type Hardness of Calcium - Tests to Measure of Hardness of Element Mohs HardnessĬalcium is Conductor of electricity. Now between F and F-: F- has one more electron, which causes the radius to be bigger.Refer to below table for Calcium Physical Properties Densityġ.55 g/cm3(when liquid at m.p density is $1.378 g/cm3) We know that F and F- are both smaller than the rest because they have less shells. But since Te has one shell more than Rb+ is it bigger. We know that Te is smaller that Rb because of the trend of decreasing radius to the right within a period. Another reasoning is that since Rb+ has the same number of protons but less electrons, the electrons are held more tightly in Rb+. We know that Rb+ is smaller than Rb because it loses an electron and has one less shell. Rb and Te are in period 5, and F is in period 2. List the following species in order of increasing size: Rb, Rb+, F, F-, Te.įirst look in which periods the element is located. K+ and Ca 2+įor isoelectronic cations, the more positive the ionic charge, the smaller the ionic radius.įor isoelectronic anions, the more negative the ionic charge, the larger the ionic radius. This creates a larger negative charge in the electron cloud than positive charge in the nucleus, causing the electron cloud to 'puff out' a little bit as an ion.Ĭations (or anions) of different elements are said to be **isoelectronic** if they both have the same electronic configuration e.g. Why? Generally, non-metals gain electrons to achieve the octet. Non-metals - the atomic radius of a non-metal is generally smaller than the ionic radius of the same element. This creates a larger positive charge in the nucleus than the negative charge in the electron cloud, causing the electron cloud to be drawn a little closer to the nucleus as an ion. Why? Generally, metals loose electrons to achieve the octet. Metals - the atomic radius of a metal is generally larger than the ionic radius of the same element.
