Why do individual electron orbitals look the way that they do?
Individual electron orbitals are described by mathematical equations that represent the probability of finding an electron in a specific region around the nucleus. The shapes of the orbitals result from the wave nature of electrons and their interactions with the nucleus and other electrons, leading to stable and energetically favorable distributions of electron density. Each orbital shape reflects the geometry of the electron distribution that minimizes repulsions and maximizes stability.
What is the difference between orbital notation and electron configuration?
In orbital notation, electron placement is represented by arrows within individual orbitals, while electron configuration represents the distribution of electrons among the orbitals in an atom or ion using a numerical system of energy levels. Orbital notation provides a visual representation of electron distribution within an atom or ion, while electron configuration provides a standardized way to express the distribution of electrons throughout an atom.
Why does a 4s electron have higher energy than a 3d electron in a chromium atom?
A 4s electron has higher energy than a 3d electron in a chromium atom because of the way electrons fill energy levels. In chromium, the 4s orbital is filled before the 3d orbital due to the stability gained from having a half-filled or fully-filled d orbital. This results in the 4s electron having higher energy than the 3d electron in a chromium atom.
In what way does an orbit differ from an orbital?
An orbit is the path an object takes around another object, like a planet around a star. An orbital is the specific region around an atom where an electron is likely to be found.
What is the electron configuration of an element?
The electron configuration of an element shows the number of electrons in their energy levels and orbitals. For example, the electron configuration of a neutral magnesium atom, Mg, with 12 electrons, is 1s22s22p63s2. This means that there are two electrons in the s orbital of the first energy level, two electrons in the s orbital and six electrons in the p orbital of the second energy level, and two electrons in the s orbital of the third energy level. The number in front of each letter represents the energy level, the letter represents the orbital, and the superscripts represent the number of electrons in the orbital.
Is there a way to draw Bohr diagrams for diatomic molecules?
Bohr diagrams represent the electron shells of individual atoms, so they are not typically used for diatomic molecules, which involve two atoms sharing electrons to form a bond. Lewis structures or molecular orbital diagrams are more commonly used to represent the electron distribution in diatomic molecules.
What is the condensed electron configuration for Cs using the appropriate noble gas core abbreviations?
The condensed version (which you want to use for cesium!) is [Xe]6s1 It means cesium has all the electrons in the same places that xenon has, plus one valence electron way out in the 6th level.
If the spin of one electron orbital is clockwise what is the spin of the other electron in that orbital?
According to Pauli's Exclusion principle it will be having anticlock wise spin if it is in the same orbital. Because no two electrons can have all the four(always spin is half) quantum number same. By the way, I don't think anyone actually calls them "clockwise" and "counterclockwise". It's usually "up" and "down" or "plus one-half" and "minus one-half".

Which is the negatively charged part of an atom called?
This is called an electron. It is a tiny subparticle floating around the nucleus in what are knwon as orbitals. There are 2 electrons MAX per orbital, although electrons erpel each other, so if there is enough space to put one electron in every orbital and have them spread out, then the electrons prefer it that way.
Why is the first ionization energy of arsenic is greater than the first ionization energy of germanium because?
There's two ways to answer this question. First electron configurations with half-filled sublevels are more stable then electron configurations that don't have half-filled sublevels. Since Selenium is one elctron away from achieving a more stable half-filled sublevel configuration it more readily gives up it's outermost electron, so less energy is requires to remove the outermost electron. Arsenic already has the stable configuration of half-filled sublevel so it wouldn't give up it's electron as readily, so more energy is required to remove it. Another way to look at it is that Selenium's outermost electron is in a p orbital that already has an electron so there is electron electron repulsion present in that orbital so it's attraction to the nucleus is less which is why less energy is required to remove it so the ionization energy is less. Arsenic has it's outermost electron unpaired in the p orbital so there is no electron electron repulsion present in that orbital so more energy is required to remove it then for Selenium's outer most electron. Hope this helps!
Electrons are found the nucleus?
Yes, though interestingly the probability density for finding an s orbital electron is actually higher in the nucleus than anywhere else (this assumes the nucleus and electron are point masses; in reality, they aren't, so it doesn't quite work out that way in the real world).
