What is the number of electrons shared between the atoms in a molecule of fluorine F2?
The diatomic fluorine molecule (F2) contains a single shared pair of electrons. Each F atom also has three pair of electrons that are not shared with the other atom. A lone pair is a pair of electrons in a Lewis electron-dot structure that is not shared between atoms.
How many valence electrons are in two fluorine atoms?
What type of bond is fluorine and fluorine?
How many valence electrons are in each fluorine atom?
seven valence electrons
How many p electrons does fluorine have?
So… for the element of FLUORINE, you already know that the atomic number tells you the number of electrons. That means there are 9 electrons in a fluorine atom. Looking at the picture, you can see there are two electrons in shell one and seven in shell two.
How many electrons does a fluorine atom need to share to become stable?
Which is more reactive fluorine or iodine?
Rather, fluorine is the most reactive halogen. It reacts violently with almost all chemicals. It shows that the B.D.E value of iodine (151 kJ/mol) is less than that of fluorine (158 kJ/mol). So, iodine should be the most reactive halogen and not halogen.
Why is iodine less reactive than chlorine?
Cl can gain an electron more easily than iodine – Cl more reactive. This is because Cl is higher up Group 7 than iodine (Cl: 2,8,7 electron configuration). Cl outer shell closer to nucleus (and less shielded) than iodine outer shell. Therefore Cl has greater attraction for an electron.
Which one of the following is the most reactive bromine iodine chlorine fluorine?
Among the halogens, fluorine, chlorine, bromine, and iodine, fluorine is the most reactive one.
Why is Cl more reactive than Br?
Although the bromine nucleus is more positively charged than the chlorine nucleus, the increase in the radius and the extra shielding in the bromine atom outweigh this factor, which means that an electron is more easily attracted into the outer shell of a chlorine atom than that of a bromine atom, so chlorine is more …
Is Br or Cl more stable?
Bromine radical, being less reactive, is more selective for the 2° radical. Cl•, being less stable and more reactive, is less choosy and less selective.
Is Cl or Br more electronegative?
At the bottom left corner of the periodic table lies Cesium, which lacks a catchy nickname [but has attracted a strangely devoted following] with an electronegativity of 0.79….Carbon is More Electronegative Than You Think.
Which is more reactive Br or Cl?
Yes, chlorine is more reactive than bromine because the chlorine atom has fewer shells and the electronic bonding is much stronger. The electrons are held closer to the nucleus. It is easier for chlorine to attract and hold electrons in its outer shell forming stronger bonds with other atoms.
Is BR stable?
Bromine has two stable isotopes, 79Br and 81Br. The most stable bromine radioisotope is 77Br (t1/2 = 57.04 h).
Is Cl A chlorine?
Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature.
Is gold very reactive?
Gold is one of the least reactive elements on the Periodic Table. It doesn’t react with oxygen, so it never rusts or corrodes. Gold is unaffected by air, water, alkalis and all acids except aqua regia (a mixture of hydrochloric acid and nitric acid) which can dissolve gold. Gold does react with halogens.
Why is gold not very reactive?
Since the 6s orbital with one electron is contracted, this electron is more tightly bound to the nucleus and less available for bonding with other atoms. The 4f and 5d orbitals expand, but can’t be involved in bond formation since they are completely filled. This is why gold is relatively unreactive.
Why is gold and silver least reactive?
silver and gold is a good conductor of electricity because of its sea of delocalised electrons between the layers of metal ions. However it is not highly reactive because you would need a lot of energy to break the metallic bonds within each of those layers.
Why is gold stable?
Because gold is the only international currency that can’t be debased, people around the world keep holding on to it as a store of value. This makes gold the most stable currency in the long-term. Since the 1930s, when the U.S. dollar has been slowly decoupled from gold, the dollar lost 99% of its value against gold.
Is gold value stable?
Although the price of gold can be volatile in the short term, it has always maintained its value over the long term. Through the years, it has served as a hedge against inflation and the erosion of major currencies, and thus is an investment well worth considering.
Is money based on gold?
The gold standard is a monetary system where a country’s currency or paper money has a value directly linked to gold. For example, if the U.S. sets the price of gold at $500 an ounce, the value of the dollar would be 1/500th of an ounce of gold. The gold standard is not currently used by any government.
Is Gold more valuable than money?
Gold historically holds its value – its purchasing power – over time. So if the US$ loses fx value, then the dollar price of gold will increase, so if you have gold and need dollars you can probably sell your gold for a lot more dollars than you paid to buy it.
