What element would form an ionic bond with fluorine?
Which of the following pairs of elements is most likely to form an ionic compound?
While the other pairs, sodium and potassium are the metals, nitrogen and iodine, chlorine and bromine, helium and oxygen are the non-metals. They do not form ionic bond. Hence, the correct pairs of elements likely to form ionic compounds are, potassium and sulfur, magnesium and chlorine.
Does fluorine and lithium form an ionic compound?
Lithium (left) and fluorine (right) form an ionic compound called lithium fluoride.

What happens when lithium reacts with fluorine?
Lithium Fluoride One lithium (Li) atom can combine with one fluorine (F) atom. Together, they make the formula LiF. Lithium gives up its one electron to make both atoms happy. So the fluorine atom has eight electrons, and a filled outer shell.
Does lithium react with aluminum?
The combustion of lithium–aluminum alloys was investigated by experiment and with a computational flame model. Experimental results show that the lithium burns in the vapor phase and aluminum reacts on the surface or in the bulk phase to form γ-LiAlO2 and β-Li5AlO4. …
What does lithium react violently with?
Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen. The colourless solution is highly alkalic. The exothermal reactions lasts longer than the reaction of sodium and water, which is directly below lithium in the periodic chart.
What happens when lithium reacts with chlorine?
Chlorine pulls one electron from lithium. It ionises- that is to say it loses an electron to form a Li+ ion. This electron is then transferred to the chlorine atom, which becomes a Cl- ion. These ions then attract each other (opposite charges attract) to form LiCl.
Why is lithium anomalous Behaviour?
Lithium shows anomalous behavior due to its small size. The polarizing power of lithium ion is highest of all the alkali metal ion . Because of small size, Lithium is very hard, less reactive as compare to other alkali metals like sodium and potassium.
Why Lithium is the strongest reducing agent?
Lithium ion is small in size on account of which more solvent molecules can easily surround around the cationic sphere. so, large amount of hydration energy is released and on account of Large amount of hydration energy makes it strongest reducing agent inspite of its highest ionisation enthalpy.
What is an anomalous Behaviour?
Anomalous behavior is a behavior that is different from its original order. It shows different properties from other members of its groups. Elements that show anomalous behavior have unique properties and form different compounds.
What is anomalous Behaviour in chemistry?
Anomalous behaviour of an element refers to the deviation of the properties and behaviour of an element from its usual or normal behaviour. It is due to the following reasons: (i) Exceptionally small size of its atom and ion.
What is the anomalous Behaviour of fluorine?
The anomalous behaviour of fluorine is due to its small size, highest electronegativity, low F-F bond dissociation enthalpy, and non availability of d- orbitals in valence shell. Most of the reactions of fluorine are exothermic (due to the small and strong bond formed by it with other elements).
Why does the first element shows anomalous Behaviour?
The anomalous behavior of every first element in a group is due to the non availability of d-orbital in their valence shell, small size, high electronegativity… Just like carbon, it doesn’t have d-orvital like the remaining members of group 4,so can’t expand it’s covalency to accept more than 4 pairs of electrons.
What is an anomalous element?
What is an anomalous pair of elements? Anomalous pairs are those pairs of elements which have not obeyed the increasing order of atomic masses. Mendeleev placed these elements in properties, and not in the increasing order of their atomic mass, according to similarity.
What element is not a transition metal?
Not all d block elements count as transition metals! A transition metal is one that forms one or more stable ions which have incompletely filled d orbitals. On the basis of this definition, scandium and zinc do not count as transition metals – even though they are members of the d block.
Why are there exceptions to electron configurations?
Exceptions are based on the fact that half-full or full shells or subshells are more stable than partially filled ones. When the difference in energy levels between two subshells is small, an electron may transfer to the higher level shell to fill or half-fill it.
Why Period 2 elements are called bridge elements?
the period 2 element is known as bridge element because they show similarity in properties with elements of next group and subsequent period. for eg beryllium to aluminium.
What are Period 2 elements called?
The second period contains the elements lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, and neon. In a quantum mechanical description of atomic structure, this period corresponds to the filling of the second (n = 2) shell, more specifically its 2s and 2p subshells.
What is a normal element?
✨Any element found in the s and p blocks in the periodic table are known as normal elements. ✔These elements have incomplete outermost shell. ✔✔Elements belonging to the s- and p-blocks in the periodic table are called the normal elements or main group elements.
What are normal elements and harmful elements?
The elements that do not give out any harmful radiations are called Normal Elements. Example: Fluorine (F), Chlorine (Cl), Bromine (Br), etc. Whereas, the elements that give out harmful radiations are called Radioactive Elements. Example: Uranium (U), Thorium (Th), Potassium (K), etc.
What is the general electronic configuration of P-block elements?
The general electronic configuration of p-block elements is ns2np1-6.
Why are they called P-block elements?
The s-block and p-block elements are so called because their valence electrons are in an s orbital or p orbital respectively. They are also called Typical Elements to distinguish them from the transition and inner transition series.
