What is a compound with 2 ions and the -1 anion has 8 more electrons than the cation?
NaCl - Na+ has 10 electrons and Cl- has 18 electrons
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
Why are noble gases less reactive than halogens?
Noble gases all have 8 electrons in their outter most energy level. when an atom has 8 electrons in it's outtermost layer, then its more stable
How many electrons can fit on the 2nd energy level?
Generally, 8 or less electrons may only inhabit the second ring.
Why is the electron BF3 deficient?
The central atom B has less than 8 electrons in the valence shell. BF3 has a tendency to accept electron pair.
Why are carbon nitrogen oxygen sulfur phosphorous hydrogen the 6 most important element of organic compound?
They have less slightly less than 8 valiance electrons.
What is a compound with 2 ions and the -1 anion has 8 more electrons than the cation?
NaCl - Na+ has 10 electrons and Cl- has 18 electrons
Which is more likely to form bonds an atom with 8valence electrons or an atom with fewer then 8 valence electrons?
An atom that has fewer than 8 valence electrons is more reactive, or more likely to form bonds, than an atom with 8 valence electron. Atoms bond by gaining, losing, or sharing electrons in order to have a filled outermost energy level with 8 valence electrons.
When an atom or an ion has 8 valence electrons it is more or less stable than when it ha fewer than eight valence electrons?
Valence electrons are the amount of electrons in the outermost electron shell. 8 valence electrons fill the outer shell making it completely stable.
What elements have less than eight valence electrons?
Any element except the elements in group 8, 9, 10, 11, 12 and 18 have lesser than 8 valence electrons.
Which atoms have a full set of valence electrons that's less than 8?
All of them. Except the noble gases.
Why are noble gases less reactive than halogens?
Noble gases all have 8 electrons in their outter most energy level. when an atom has 8 electrons in it's outtermost layer, then its more stable
Is xenon more or less reactive than bromine why?
Xenon is less reactive. Bromine has 7 electrons in its valency shell and so readily forms a negative ion. Xenon has 8 electrons and so is inert.
Is -8 greater than 8 or less than?
-8 is less than 8
Is -8 greter then 8?
-8 is less than all positive numbers, including 8. -8 is 8 less than 0, and 0 is eight less than 8.
How many electrons can fit on the 2nd energy level?
Generally, 8 or less electrons may only inhabit the second ring.
How do you calculate the valency of an element from its electronic configuration?
first we will make the shells as required then if the outer shell is going to have less than 8 electrons we will minus it from 8 and there comes our valancy
