How many valence electrons does an atom of oxygen have and what noble 1 point gas will it be most like after forming a chemical bond? *
1)8 electrons and neon
2)2 electrons and fluorine
3)6 electrons and neon
4)6 electrons and argon

3)6 electrons and neon

In an atom there are levels of energy in the shell and sub shell  

This energy level is expressed in the form of electron configurations.  

The electron configuration Oxygen (atomic number = 8) :

1s²2s²2p⁴

Oxygen will try to achieve stability (according to the octet rule) by binding 2 electrons so that the 2p orbits are filled with 6 electrons, so that the configuration is stable like the noble gases Neon

₁₀Ne = 1s² 2s² 2p⁶

have a great day because if you dont you and i will be sad

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
