Monatomic ion
| Common type I cations | |
|---|---|
| Hydrogen | H+ |
| Lithium | Li+ |
| Sodium | Na+ |
| Potassium | K+ |
What is the most stable monatomic ion formed from?
If two electrons are removed, it will achieve the configuration of noble gas, neon. Thus, the most stable monatomic ion formed by magnesium is Mg2+ M g 2 + .
What makes a monatomic ion stable?
For example, NaCl forms the monatomic ions Na+ and Cl- when it dissolves in water. Atoms form this monatomic ions so they have the most stable electron configuration. Monatomic ions tend toward having half-filled or completely-filled valence electron shells. Adding energy also forms monatomic ions.
Is LiF most stable?
Solution : Because of the small size of Li, LiF has highest lattice enthalpy and hence most stable.
Which of the following is least stable Li?
Be− is the least stable ion.
What does Li+ mean in chemistry?
Lithium-ion Lithium-ion (Li+, Li-Ion, Lion) cells are generally used as power sources for portable equipment. They are usually rechargeable. Lithium-ion and nickel-metal-hydride (NiMH) have displaced nickel-cadmium (NiCd or nicad) as the dominant rechargeable chemistry for portable applications.
How do you find monatomic ions?
Cations are positively charged ions formed when neutral atoms lose electrons; anions are negatively charged ions formed when neutral atoms gain electrons. It is possible to predict the charges of common monatomic ions by looking at the group numbers on the periodic table.
What is an example of a monatomic ion?
Some examples of monatomic ions are sodium ions and hydrogen ions that have positive charges. Hydride ions, chloride ions, and oxide ions are a few examples of monatomic anions.
What are examples of monatomic ions?
Some examples of monatomic ions are sodium ions and hydrogen ions that have positive charges. Hydride ions, chloride ions, and oxide ions are a few examples of monatomic anions.
Which is most stable LiF LiCl LIBR LII?
LiFLiClLiBrLiI. Solution : Because of the small size of Li, LiF has highest lattice enthalpy and hence most stable.
Why is lithium hydride more stable?
Due to the small size of $L{i^ + }$ , the lattice energy of LiH is greater. As the size of the ion is small it has more force of attraction and hence it requires a lot of energy to break the bond and therefore it is more stable.
Which ion is least stable Li +/ be -/ B -/ C?
Be− is the least stable ion.
Is be more stable than Li?
Now there is one electron in the P orbital which makes it very less stable. There are two electrons in the P orbital. It makes it unstable than Lithium but more stable than Beryllium. It has a half filled P orbital which makes it very stable.
How many stable electrons does lithium have?
NOTE: Lithium has only one electron in its outermost shell. To gain stable configuration it will need to gain seven electrons.
What is the charge of a stable lithium ion?
A lithium atom has 3 protons and 3 electrons. It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion.
What is monatomic and examples?
Monatomic definition Occurring as single atoms. Helium is a monatomic gas. adjective. 2. (chemistry) Of an element, consisting of a single atom in the molecule; for example: the noble gases.
How do you write monatomic ions?
Monatomic Cations: The first type is named simply by using the element name followed by the separate word ion. Monatomic cations with a single possible charge. These ions are limited to the Group IA (alkali metals, +1), Group IIA (alkaline metals, +2), zinc (Zn2+), aluminum (Al3+), and silver (Ag+).
Which molecules are monoatomic?
Monoatomic (monatomic): A molecule composed of just one atom, and lacking any covalent bonds. The noble gases (He, Ne, Ar, Kr, Xe, and Rn) are all monoatomic, whereas most other gases are at least diatomic.
How do you identify a monatomic ion?

Which of the following has highest enthalpy of formation a LiCl B LiBr C LiF and LiI?
LiCl has highest lattice enthalpy. Because the Li+ ion is smaller than the Na+ ion, the Coulombic attractions between ions in LiCl are stronger than in NaCl. This results in a greater lattice enthalpy.
Which has more lattice energy LiCl or LiF?
So, the correct order of lattice energy is LiI<LiBr<LiCl<LiF.
Which hydride is most stable NaH KH CsH LiH?
Thus, (LiH)is the most stable hydride among(LiH),(NaH),(CsH)and(KH). Thus the correct answer to the given question is option (1). Note: On the basis of size, (LiH) is the most stable hydride. Hydrides are used as reducing agents in many chemical industries and are also used as drying agents.
Is lithium hydride stable?
Lithium hydride is a crystalline material that is a relatively stable compound.
Which is more stable B or C?
Correct Option : B.
Which is more stable Li2 or Li2+?
Li2+ is more stable than Li2− because Li2− has more numbers of antibonding electrons.
Why is lithium so stable?
Solution : Lithium ion being very small in size with more charge density polarises the bigger carbonate ion and distoris, it. So it dissociates forming stable `Li_(2)O`. <br> `Li_(2)CO_(3) to Li_(2)O +CO_(2)`. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams.
How many electrons will the lithium atom give up to become stable quizlet?
a. Lithium is the most stable element because it has to lose only one electron to achieve a stable configuration.
How many electrons does Li+ cation have?
However, in this question we are being asked the electrons in a lithium ion. Lithium, as a metal, donates electrons and so must have lost an ion in order to have a +1 charge. Therefore, the number of electrons must be 2.
Is lithium more stable?
Due to the small size of $L{i^ + }$ , the lattice energy of LiH is greater. As the size of the ion is small it has more force of attraction and hence it requires a lot of energy to break the bond and therefore it is more stable. Now, let's discuss some of the properties of lithium. Hence, option A is correct.
