how many electrons are there in the first and the second shell or orbit of oxygen?
476858
There are 8 electrons in an oxygen atom.  The first shell can hold up to 2, so this leaves 6 for the second shell.  The second shell can hold up to 8, which is what happens when oxygen becomes an oxide ion.  It gains two electrons and obtains a -2 charge, and has an electron configuration identical to that of neon.

a) 36\nb) i just found the answer for b : it is 6 because its a p orbital

yes you are right.. there are two sets of electrons
892647
The electron configuration of Oxygen is:\n1s2\n2s2\n2p4\n\nThe valence orbital (2) has 6 electrons (2 from the 2s and 4 from the 2p).  Thus oxygen has six valence electrons.

Oxygen atoms like to form two bonds with other atoms. They will be more stable that way. It is related to the outer shell of electrons(valence electrons). Individual oxygen atoms have 6 valence atoms and would prefer to have 8(it's called the octet rule!)

Typical Oxygen is O2 and it shares 2 electrons with each other. If you need the charge it is -2 meaning it is looking to gain 2 electrons to be neutral.

the short answer is valence shell electrons.

If there are only 3 electrons, then the maximum number of orbitals in that subshell is 3. however, if you meant magnetic quantum number of +3 - as in ml = -3, -2, -1, 0, +1, +2, +3, then that's the f subshell which has 7 orbitals.

7\nf sublevel, containing seven f orbitals, which can hold a maximum of 14 electrons. Thus, the fourth level can hold up to 32 electrons: 2 in the s orbital, 6 in the three p orbitals, 10 in the five d orbitals, and 14 in the seven f orbitals.

well since o2- has an extra 2 electrons it gives it 10 electrons total making it the same electron configuration as neon which is a noble gas....so the elec. config for o2- is [Ne]

magnesium (Mg)? 1s²2s²2px²2py²2pz²3s² = 1s^2 2s^2 2p^6 3s^2\n\nthere are three kinds of p orbitals, px, py,pz,difference in geometry but all are capable of holding 2 electrons.\n\n*** \nfor those ppl thinking about fluorine, first of all, it has 2 x 6 = 12 electrons, not 9 (^^). Fluorine has five 2p electrons, this element has six; also, this element has two valance electrons (the outmost 3s orbital), not seven. So definitely NOT fluorine, I can guarantee u that. \n***

proton and neutron, the electrons are on the outer shell

eight, an element forms a compound with another element to achieve a full outer shell of electrons, in the case of sulphur, its outer shell is full with eight electrons, it achives this by sharing electrons with oxygen atoms

O\n                       ^\n                       |\n                      xx\n                  H-O-Br:->O\n                      xx\n                       |\n                       V\n                       O\n\nPlace the xx above and below Br. Br donates electron pairs to three oxygen atoms. There is also one Br-O-H bond in the molecule.

Yeah, that's right.\n\nThere are 2 atoms of O in each molecule of O2, so 1 mole of O2 molecules contains 2 moles of O atoms.

The chemical formula for Ozone is O3, meaning that it is made up of 3 bonded Oxygen atoms.\n\nBy far, the most common isotope of Oxygen is Oxygen-16, made up of 8 protons, 8 neutrons, and 8 electrons.\nSo Ozone, with 3 Oxygen atoms, would have a total of 24 protons, 24 neutrons, and 24 electrons.
