Do chlorine and fluorine have the same number of valence electrons?

All three elements i.e. fluorine, chlorine and bromine have same number of valence electrons and same valency.

Do chlorine and fluorine have similar properties?

halogens: Group 17 (or VII) in the periodic table consisting of fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). They share similar chemical properties.

What are the similar properties of chlorine fluorine and bromine?

What are those similar properties ?
…
  • Fluorine , Chlorine and Bromine are non-metals with seven valence electrons .
  • They are highly electronegative elements with valency of one.
  • They exist as diatomic molecules .
  • They form ionic compounds with alkali metals.

Why are fluorine chlorine and iodine in the same group of the periodic table?

Fluorine, chlorine, bromine and iodine are placed in the same group 17 of the periodic table because they are more electronegative.

What do fluorine and chlorine have in common?

What Makes Them Similar? When you look at our descriptions of the elements fluorine and chlorine, you will see that they both have seven electrons in their outer shell. That seven-electron trait applies to all of the halogens. They are all just one electron shy of having full shells.

Why is fluorine and chlorine in the same group?

Fluorine and chlorine have a valency of 1 and show similar chemical properties. So, they are placed in the same group.

Why is fluorine more reactive compared to iodine?

Some factors influencing this are: The electron affinity of fluorine is much larger, which makes reduction to fluoride much easier. E−F bonds are stronger than E−I bonds, in both an ionic and covalent sense. Fluoride has a larger solvation enthalpy than iodide.

Why chlorine is less reactive than fluorine?

Its radius is large. Its tendency to gain an electron is small as compared to fluorine. Therefore, chlorine is less reactive than fluorine.

Why does fluorine have a lower melting point than chlorine?

It has low melting and boiling points , second lowest to flourine because chlorine having a weak dipole bonds because of less electrons in chlorine . And because of less size of flourine than chlorine . so flourine has a lower m.p that chlorine..

Why is fluorine more reactive than chlorine GCSE?

The reactivity is the halogens ability to gain an electron, so number of electrons already in the atom plays a vital role. Chlorine has more electrons so repels a reacting electron with greater force than fluorine, making it less likely to react.

Why is fluorine more reactive than fluorine?

Reactivity is an elements ability to gain an electron. So the better it is at “stealing” electrons, the more reactive it will be. The thing that makes fluorine so reactive is its electronegativity. Therefore, since fluorine has a higher electronegatvity than chlorine, fluorine is more reactive.

Which one is more reactive fluorine and chlorine and why?

Fluorine atoms are smaller than chlorine atoms, thus it’s possible for electrons to be closer to the nuclei of fluorine atoms and experience a stronger attractive force with the nuclei. This allows fluorine atoms to take electrons more easily than chlorine atoms, and so fluorine is more reactive than chlorine.

Why chlorine is more reactive than chlorine?

Answer. chlorine is less reactive than fluorine because the outer electrons in a chlorine atom are further from the nucleus than the outer electrons in a fluorine atom. It is harder for a chlorine atom to gain an electron than it is for a fluorine atom.

Why is fluorine more active than chlorine although both lie in the same group?

Fluorine is more reactive. This is because the valence/bonding electrons are closer to the nucleus in Fluorine than they are Chlorine and others and thus more strongly attracted. Fluorine is most electronegative, thus it is most reactive.

Is fluorine more reactive than CL?

Fluorine is clearly more reactive than chlorine. It is arguably more reactive than any other element on the Periodic Table.

Why fluorine is the most reactive?

(3) The atomic size of flourine is the smallest among the halogens. Hence, the nuclear attraction on the outermost electrons is maximum. Hence, fluorine is the most reactive among the halogens.

Why does fluorine have lower electron affinity than chlorine?

Electron affinity of fluorine is less than that of chlorine because the atomic size of fluorine is very less than chlorine as a results there is a large electronic repulsion between the electrons of fluorine.

Why is fluorine more non metallic than chlorine?

Why flourine is more non-metallic than chlorine? … According to the periodic table, Fluorine is placed above the Chlorine. This means that Fluorine has a smaller atomic radius and its electrons are closer to the core. So the electrons attraction forces are greater and there is a lower possibility of their loss.

What is chlorine reactivity?

Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Pauling scale, behind only oxygen and fluorine.

Is chlorine highly reactive?

Halogens are notorious electron-hogs; powerfully attracting electrons from atoms of other elements, particularly from the alkali metals. This makes the halogens highly reactive. Chlorine, being one of the smaller halogens, will react strongly with most elements.

Why is fluorine more reactive than other elements?

Flourine is more reactive than any other halogen this is because the valence electrons are closer to the nucleus in fluorine than they are in chlorine and others and thus more strongly attracted. Fluorine is also the most electronegative element of the periodic table thus it the most reactive than any other halogens.

How reactive is fluorine?

fluorine (F), most reactive chemical element and the lightest member of the halogen elements, or Group 17 (Group VIIa) of the periodic table. Its chemical activity can be attributed to its extreme ability to attract electrons (it is the most electronegative element) and to the small size of its atoms.
