YOU MUST EXPLAIN/SHOW WHY (S points). The expected molecular orbital energy level (MO) diagram of the hydrogen molecule is given as: Ferromagnetic substances are almost similar to paramagnetic substances. While diamagnetic materials are weakly repelled under the influence of external magnetic fields as they have paired electrons in their orbitals. {\displaystyle \mu _{M_{J}}=M_{J}g_{J}\mu _{\mathrm {B} }-\mu _{\mathrm {B} }} The second ionization energy needed to form As(I) to As(II) is 1798 KJ/mol. If there are unpaired electrons, they will cause an attraction to an applied magnetic field (paramagnetic). H / The Such substances experience no attraction (slight repulsion) from the external magnetic field. Dr. Richard Spinney (The Ohio State University). Then figure out what the total cost of the trip would be.? Another example of paramagnetic substances is O2 gas in its molecular form because it has two unpaired electrons in its molecular orbitals as shown in the energy level diagram below. Due to the unpaired electron at the end Arsenic is a silver-grey, brittle, crystalline, and naturally occurring solid which is widely found in the earths crust. e Consequently, the lanthanide elements with incompletely filled 4f-orbitals are paramagnetic or magnetically ordered.[7]. k Fourth ionization energy= 25000 kJ/mol H Titanium ion has unpaired electrons in orbital which makes it paramagnetic. It is observed that only a small fraction of the tiny magnets are aligned in the induced magnetic field due to thermal properties. M Materials that are attracted by a strong magnet are known as paramagnetic materials. An example of data being processed may be a unique identifier stored in a cookie. Depending on the properties and position in the periodic table, the chemical classification of the element is done.
