What is a univalent cation and a trivalent cation?
The 'valency' of a cation describes the free orbitals it has to accept lewis electrons. For example, potassium is monovalent (or univalent), and only has one empty orbital to accept electrons, whereas calcium is divalent, and has two empty orbitals, (and a 2+ charge) to accept donor electrons for lewis bonding.
Is a cation isoelectric with the element before or after it?
No necessarily. Although the alkali metal cations are, most other cation-forming elements (metals) are not as many of them lose more than one electron. It is even more complicate for the transition metals as they can move electrons between their s and d orbitals.
What is an atom that will lose or gain electrons until they have a full outer shell?
Anion (if it has an almost-filled outer shell) or a cation (if only the outer S orbital is filled or partially filled)
Is lithium cation or anion?
Lithium form the cation Li2+.
What is oxonian cation?
An oxonium cation is a polyatomic cation with a charge of +1 with a central oxygen bonded to three groups or elements Examples:- H3O+ is the oxonium cation, (C2H5)3O+ is the triethyloxonium cation.
Are methyl cation is more stable than ethyl cation?
An ethyl cation is more stable because the carbon adjacent to the positively charged carbon has three sigma bond orbitals available for overlap with the vacant p orbital, whereas methyl cation does not have any sigma bond orbitals available for overlap with the vacant p orbital.

What has a 1s 1 orbital?
One option is a helium atom. Another is a Lithium cation. Or a beryllium cation. Or boron for that matter. Cause Li would be 1s2 2s1, Be would be 1s2 2s2 and Boron would be 1s2 2s2 2p1 so if they were to lose their valence electrons to become ions (cations) then they would have a 1s2 orbital. :D
Why is cyclopropyl methyl cation more stable than tpm cation?
the case of cyclopropylalkyl cation and substituted cyclopropyl cations is interesting. Cyclopropylmethyl cation has been found to be more stable than benzyl cation and the stability increases with each addition of cyclopropyl groups. This increased stability has been explained between the bent orbitals of cyclopropyl rings and the vacant p orbital of the cation carbon. The vacant p orbital lies parallel to C2-C3 bond of the cyclopropane ring and not perpendicular to it. Thus the geometry becomes similar to that of a cyclopropane ring conjugated with an olefinic bond.
Are ionic compounds flexible?
yes ionic compounds are non rigid and non directional . Ionic bonds are non directional because the number of anions surrounded a cation is limited by the efficiency of its lattice packing therefore it is not directional afterall. However in covalent bonds, notice how the orbitals overlap, side-ways or head-on which defines the bond angle. The orbitals need to overlap in a specific direction in covalent bonding unlike in ionic bonding. As for rigidity it is the same concept as directional. Ionics bonds are non rigid because no matter how you rotate an anion around a cation, the bond is not affected, it is still the same. Whereas in covalent bonds, it is difficult to rotate the bonds especially in pi bond or side-ways overlapping due to the shape of p orbitals which results in rigidity, relatively
Which one follows Fazan rule Small cation or big anion or Filled orbital or All?
small cations
From which orbital in a lithium atom is an electron transferred to form Li?
The valence electron in a lithium atom is in orbital 2s. To form a lithium cation, this electron is transferred to some more electronegative atom.
How do electron configurations become stable?
There are many types of rules for electron configuration. Look at the Aufbau principle and Hund's rules.In each orbital there is a maximum of two electrons.In a "s" orbital, there are two electrons.In a "p" orbital, there are three sub-orbitals, each containing two electrons. (Thus containing 6 electrons)In a "d" orbital, there are five sub-orbitals, each containing two electrons. (Thus containing 10 electrons)In a "f" orbital, there are seven sub-orbitals, each containing two electrons. (Thus containing 14 electrons)Look at the Aufbau diagram linked below.The coefficient represents the orbital. Do not use mathematics to try to solve the configurations.1s2 2s2 2p6 : Neon's Electron ConfigurationThe letter following the coefficient describes which type of orbital it is, being s, p, d, or f.The superscript denotes the number of electrons it contains. If you add 2, 2, and 6, you would get 10, Neon's atomic number.Electron configurations become stable when they are neutrally charged.i.e Li: 1s2 2s1This is a stable electron configuration. However, if you lose that one electron,Li: 1s2It become a positively charged ion, called a cation.
Is a cation isoelectric with the element before or after it?
No necessarily. Although the alkali metal cations are, most other cation-forming elements (metals) are not as many of them lose more than one electron. It is even more complicate for the transition metals as they can move electrons between their s and d orbitals.
What is an atom that will lose or gain electrons until they have a full outer shell?
Anion (if it has an almost-filled outer shell) or a cation (if only the outer S orbital is filled or partially filled)
What symbol for the ion is formed if lithium loses 1 electron?
ok so you'll notice that lithium is on the second row of the periodic table, this means that its the next orbital hydrogen = 1s1 orbital helium = 2s1 orbital lithium = 2s1, 1s2 orbital removing the outter electron from lithium means that lithium has lost a minus charge and therefore must have a plus charge, this is called a cation. removing the electron also means now that there are no electrons in the s2 level do lithium is left with a 2s1 orbital, this is a very stable configuration and lithium wont loose any more electrons so your lithium ion will be nucleus with 3 protons 4 neutrons and 2 electrons with a plus charge to represent the loss of an electron
Is lithium cation or anion?
Lithium form the cation Li2+.
