Table \(\PageIndex{1}\): Selected Properties of the Group 14 Elements Property Carbon Silicon Germanium Tin Lead *The configuration shown does not include filled d and f subshells. C(s, graphite) → C(s, diamond)? Sodium (Na). The elements in group 13 and group 15 form a cation with a -3 charge each. And elements in group 14 have a charge of -4. Ge-70, Ge-72 and Ge-74 can all be used for the production of the medical radioisotope Se-73, although the most common production route is via natural As (As-75). Period A horizontal row in the periodic table. Chemical elements listed by ionization energy The elements of the periodic table sorted by ionization energy. So, "Ge": 1s^(2)2s^(2)2p^(6)3s^(2)3p^(6)4s^(2)3d^(10)4p^(2) An alternative way of writing the electron configuration for Ge is by using the noble gas shorthand notation. A 0.0835 M solution of a particular monoprotic weak acid, HA, has a … Which of the following elements is in the same period as phosphorus? ... Indium (In) is a Period 5 element with one more proton than cadmium. Germanium was discovered by Clemens Alexander Winkler (DE) in 1886. Which of the following statements is true concerning the reaction below? Ge Name of Element : Germanium Atomic Weight : 72.6 Atomic Number : 32 Group : Transition Elements Electron Configuration: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p2 Go to the Top of the page. Elements in group 16 have a charge of -2, while all the elements of group 17 are halogens with a charge of -1 each. ‡ X is Cl, Br, or I. This implies that the neutral Ge atom's electron configuration must account for 32 electrons. Cu, Cd, Au, Co. To what category of elements does an element belong if it is a poor conductor of electricity? This list contains the 118 elements of chemistry. Periodic Table Packet #1 Name_____ Period_____ 6.4 c Periodic Table of Elements Directions: Use the periodic table to fill in the below chart. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. † The values cited are for six-coordinate +4 ions in the most common oxidation state, except for C 4 + and Si 4 +, for which values for the four-coordinate ion are estimated. Natural GeF4 is used in the semiconductor pre-amorphisation implant process. The use of Ge-72, in the form of GeF4, improves this process and reduces contamination. Germanium Basic Facts .
