What else can I help you with?
Helium and neon cant form compounds with fluorine why?
Helium and neon are noble gases, which have full valence shells of electrons and are highly stable. They do not readily form compounds with other elements, including fluorine, because they have little tendency to gain or lose electrons to form chemical bonds. This makes them unreactive and inert.
How many valance electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
What element has the greatest electronegativity?
Fluorine... by far. Its so electronegative that it will never form double bonds, even if they would make sense by the octet rule. BF3 is a really good example of this
Is the ionization energy of chlorine higher than that of fluorine?
In the periodic table of elements, fluorine and iodine are in the same column, but fluorine is in the second, iodine in the fifth row. That means fluorine has only nine electrons flying around in orbitals while iodine has 53 of them. Ionization is the called a process during which a single electron is abstracted - we're now talking about the 1st ionization energy, which is much higher for fluorine. Well, as it only has nine electrons scattered in the orbitals (but according laws, of course), they do not really influence the repelling - attracting actions between the positive center and the other electrons beside them. For iodine with 53 electrons, they really do interfere with the attraction of other electrons AND as the outmost electrons (which are the ones taken away by ionization) are in those orbitals which are at the biggest distance to the center - for 53 electrons the outmost orbitals is at a much bigger distance... both results in a smaller attraction of the electrions at max distance from the center... so for iodine you need less energy to perform ionization.
What noble gas possesses 6 electrons in the 6th energy level?
No noble gas possesses 6 electrons in the 6th energy level. Noble gases have a stable electron configuration with a full valence shell. Helium has 2 electrons in its first and only energy level, while neon has 10 electrons in its second energy level.
What element has 2 electrons in the second ring?
The element with 2 electrons in the second ring is helium. Helium has 2 electrons in its second energy level.
How is fluorine different from helium?
Fluorine is a chemical element with atomic number 9, while helium is element number 2. Fluorine is a highly reactive nonmetal, while helium is a noble gas known for its inertness. Fluorine is commonly found in compounds like fluorides, while helium is often used in balloons and cryogenics due to its low boiling point.
Which element has a full outermost energy level containing two electrons?
Helium (He)
What type of bond is helium and fluorine?
It would be most logical to say: none. Helium is a noble gas, and it is stable (it has the maximum amount of electrons in its outer energy level). That means it's "happy" and doesn't want to hook up with any elements... However, researchers have bombarded Helium atoms with electrons, those electron ended up in the second layer of electrons an element can have, if they fill it up with 8 electrons, once again, helium doesn't do anything. But if they fill it with five electrons, fluorine could attach to it, and you would get the molecule F3He. Though of course, without the multimillion dollar high-tech laboratory the scientists who've made helium bonds had, you'd have no chance of making it, because in nature, it is impossible.
Which element is most reactive lithium carbon fluorine or helium?
The most reactive is fluorine.
Helium and neon cant form compounds with fluorine why?
Helium and neon are noble gases, which have full valence shells of electrons and are highly stable. They do not readily form compounds with other elements, including fluorine, because they have little tendency to gain or lose electrons to form chemical bonds. This makes them unreactive and inert.
What element could have two electrons in their outermost level and be full?
Helium has only 2 electrons and its energy level is full.
What element when combined with fluorine would produce the most non polar covalent bond?
When combined with fluorine, helium would produce the most nonpolar covalent bond. This is because helium has a full valence shell with two electrons, making it highly stable and unlikely to share electrons with fluorine.
What element has atoms with only one completely filled principal energy level?
undiscovered...yet, but there are a few...go forward 50 years and see
Which element has a full outermost energy level contining only two electrons?
Helium has a full outermost energy level containing only two electrons.
What is the number of valence electrons the element helium has?
Helium has 2 electrons (total of 2 electrons and 2 valence electrons)
Helium atoms only need how many valence electrons to have a filled outermost energy level?
Helium atoms only need 2 valence electrons to have a filled outermost energy level because helium is in the first period of the periodic table and its outermost energy level can only hold a maximum of 2 electrons.
