A 2-mm-diameter copper ball is charged to plus 50 nC What fraction of its electrons have been removed?
To find the fraction of electrons removed, we need to calculate the total charge of the copper ball when neutral, then compare it to the charge when +50 nC. Each electron has a charge of -1.6 x 10^-19 C. The number of electrons removed can be found by dividing the difference in charge by the charge of an electron. This will give us the fraction of electrons removed.
Why don't the noble gases form covalent compounds?
*sigh*Noble gases have one complete outer shell (eight electrons) excluding helium, which has two. this makes them extremely unreactive. however, experiments have been done, and under extreme heat and pressure, helium make react with oxygen (six+two) this is so unstable that it lasts for less than a few seconds. This is why helium may react in the sun.
Why do noble gases not react with other compounds and elements?
Noble gases don't react with other elements because of the stability of the outer hell. Helium has 2 electrons , 1s2 a full shell. the restt have an outer shell of 8 electrons the "octet". This gives neon a full valence shell, the rest of the heavier noble gases have an outer shell with 8 electrons which while it is is very stable and makes these gases very un-reactive it is not full.Compounds have been made for the noble gases heavier than neon. These compounds are all unstable and highly reactive and the first a xenon fluoride was made in 1962.
How many electrons can the element helium lend?
In theory 2 but in practice this has never been found. Helium is extremely stable and holds on to its electrons and does not share or "lend" them.
Does noble gases have the maximum number of electrons in their outer energy level?
No. Only helium and neon have full outer shells- the rest just have 8 electrons filling the s and p orbitals- interestingly it is these heavier elements for which compounds have been prepared.
What is the stable electron arrangement of sodium after the 3s sublevel electrons been removed?
The stable electron arrangement of sodium after the 3s sublevel electrons have been removed is the noble gas configuration of neon. Sodium loses one electron to achieve a full outer shell, similar to the electron configuration of the nearest noble gas element.
Air has been removed and electrons flow?
air has been removed and electrons flow
What is the charge on the tin atom if four electrons have been removed?
The charge on the tin atom would be +4 if four electrons have been removed. This is because each electron carries a negative charge of -1, so removing four electrons results in a net positive charge of +4 on the atom.

What is a sentence with the word resemble in it?
The suspects resemble an old style gang.The photos of the older couple resemble my parents.Two possible sentences for 'resemble' would be:Although in the same Order of animals, a koala and a wombat do not resemble each other at all.I have been told that I resemble my brother in appearance.

Is the helium ion positive or negative?
If one electron has been removed from Helium's electron shell then it is a He+ ion. If both of its electrons have been removed it becomes a He2+ ion. Either way they are both positive ions.
Is nitrogen and oxygen noble gases?
The term noble is old and today inadequate.The so-called noble gases have the outer electron shell full, with 8 electrons; this structure lead to a very low chemical reactivity but now they are not all considered as inert elements.Compounds have been made with Krypton, Xenon and Radon. None have yet been made for Argon, Neon or Helium.
What animal do you resemble if you've been described as corvine?
