Example PageIndex{1} Ranking Ionization Energies Predict the order of increasing energy for the following processes IE 1 for Al IE 1 for Tl IE 2 for Na IE 3 for Solution Removing the 6p 1 electron from Tl is easier than removing the 3p 1 electron from Al because the higher n orbital is farther from the nucleus so IE 1 Tl < IE 1 Al Ionizing the third electron from
For atoms with partially filled d or f subshells these electrons are typically omitted from Lewis electron dot diagrams For example the electron dot diagram for iron valence shell configuration 4s 2 3d 6 is as follows Elements in the same column of the periodic table have similar Lewis electron dot diagrams because they have the same valence shell electron configuration

How Is Hail Formed Diagram Hail is a type of frozen precipitation that falls from the sky usually during thunderstorms It is formed when drops of water freeze in the atmosphere and become large enough to fall to the ground The formation of hail is a complex process that involves several steps which can be illustrated with a hail formation
The same rule will apply to transition metals when forming ions You should note that the ns electrons are always lost before the n 1 d when forming cations for transition example the electron configuration for Zn [Ar]4s 2 3d 10 the electron configuration for Zn 2 [Ar]3d 10 The transition metals still do not end up being isoelectronic with a noble gas but the loss of two
Consequently the size of the region of space occupied by electrons decreases and the ion shrinks compare Li at 167 pm with Li at 76 pm If different numbers of electrons can be removed to produce ions with different charges the ion with the greatest positive charge is the smallest compare Fe 2 at 78 pm with Fe 3 at pm
The energy released when an electron is added to the neutral atom and a negative ion is formed Electronegativity Pauling scale The tendency of an atom to attract electrons towards itself expressed on a relative scale heated to 100 o C but it will react with nitrogen from the atmosphere to form a red brown compound lithium nitride Li 3 N

Recipe for a Hurricane Whipping up a hurricane calls for a number of ingredients readily available in tropical areas A pre existing weather disturbance A hurricane often starts out as a tropical wave ; Warm water Water at least degrees Celsius over a depth of 50 meters powers the storm ; Thunderstorm activity Thunderstorms turn ocean heat into hurricane fuel

For our sodium example the symbol [Ne] represents core electrons 1s 2 2s 2 2p 6 and our abbreviated or condensed configuration is [Ne]3s 1 The alkali metal sodium atomic number 11 has one more electron than the neon atom This electron must go into the lowest energy subshell available the 3s orbital giving a 1s 2 2s 2 2p 6 3s 1

The eutectoid reaction The eutectoid reaction describes the phase transformation of one solid into two different solids In the Fe C system there is a eutectoid point at approximately % C 723°C The phase just above the eutectoid temperature for plain carbon steels is known as austenite or gamma
Vanadium oxides with multioxidation states and various crystalline structures offer unique electrical optical optoelectronic and magnetic properties which could be manipulated for various applications For the past 30 years significant efforts have been made to study the fundamental science and explore the potential for vanadium oxide materials in ion

Orbital Diagrams An orbital diagram like those shown above is a visual way to reconstruct the electron configuration by showing each of the separate orbitals and the spins on the electrons This is done by first determining the subshell s p d or f then drawing in each electron according to the stated rules above

The LiAl and Li 2 Al intermetallic phases are ordered compounds where the atoms order on sublattices thus changing the symmetry of the material The ordered phases show limited solubility where for instance the extra Li will occupy sites where an Al usually sits or occupies an interstitial position LiAl Li 2 Al
Urine is formed in three main steps glomerular filtration reabsorption and secretion It comprises 95 % water and 5% wastes such as ions of sodium potassium and calcium and nitrogenous wastes such as creatinine urea and ammonia Osmoregulation is the process of maintaining homeostasis of the body
An Atoll Reef is a ring like shaped coral reef or small islands of reefs in a circle with a lagoon in the middle and are usually located in the middle of the sea These types of reefs are formed when an island has sunk completely or nearly in the middle of the ocean from rising sea levels around a pre existing structure these islands are often the tops of underwater volcanoes
