How many electrons are lost or gained in the element o when they form ions?
atoms gain and lose electrons, so they can have a full outer shell of 8 electrons (or two electrons if its the innermost shell) when atoms lose electrons it is called oxidation and when they gain electrons they are said to be reduced. OIL RIG is most commonly used to help remember that oxidation is loss and reduction is gain of electons. when atoms lose electrons they are left with a positive charge and when they can electrons they have a negative charge.
Do all atoms tend to lose electrons?
When atoms combine with other atoms, some times they lose electrons, some times they gain electrons, and some times they share electrons. In an ionic bond, one atom will lose an electron(s), and the other will gain an electron(s). An example might be NaCl where Na loses an electron and Cl gains an electron. In a covalent bond, each atom provides an electron and both of them share the two electrons. An example of this might be H2O where each hydrogen provides one electron, and oxygen provides one electron to make the O-H bond.
What would have to gain two electrons in order to achieve the same number of electrons as a noble gas O or Sr or Na or Se or Br?
Oxygen, O ,and selenium Se. O (oxygen) would have to gain two electrons in order to achieve the same number of electrons as Ne (neon, a noble gas). Selenium would gain two to achieve the same number of electrons as Kr, krypton (noble gas). They would form the oxide, O2- and selenide Se2- ions
How many electrons does O need to achieve noble gas?
Oxygen should gain 2 electrons to achieve noble gas configuration
How could each what atoms react to achieve a noble gas configuration?
if the atom is an element from groups 1, 2, or 13, the atom has to give up electrons to make it have 8. For example, if you have Boron in group 13, it has 3 valence electrons, making it more likely to give up electrons than gain them. If you take 3 electrons from Boron, you get Helium. Helium is the noble-gas for Boron. B(+3) has a noble-gas configuration of He. if the atom is an element from groups 15, 16, or 17, the atom has to gain electrons to make it have 8. For example, if you have Oxygen with 6 valence electrons, it is more likely to gain electrons than lose them. If 2 electrons are added to Oxygen the noble-gas configuration becomes Neon. O(-2) has a noble-gas configuration of Ne. if the atom is an element in group 14, it can either gain or lose electrons. so the noble gas configuration could be the 4 electrons less or 4 electrons more than it. For example, if you add 4 electrons to Carbon you get Neon but if you take away 4 electrons you get Helium.
What atoms tend to gain two electrons to form a 2- anion?
se and sometimes gain electrons. Atoms with eight valence electrons do not easily lose electrons

Atoms that have or electrons in their valence shells tend to gain electrons to form charged ions?
an ion.
What ion would be formed from oxygen how many electrons would be lost or gained?
Oxygen is in group 6, and so it has 6 valence electrons. It needs to more to make an octet, so it will GAIN TWO electrons, and become negative 2, i.e. O^2-.
Information about some atom gain electrons and what is the important of this?
Non-metals, in the upper right hand region of the periodic table (B, C, N, O, etc.), tend to gain electrons. This leaves them negatively charged and they are called anions.
If 2 electrons where added to oxygen atom what would be the charge?
All atoms have a neutral charge until they lose or gain electrons. Once they lose/gain electrons then they are considered ions. Gaining electrons- If atoms gain electrons then they are getting negatively charged particles making them have a negative charge. Losing electrons- If atoms lose electrons then they are losing a negative charge and they become a positively charged ion. Oxygen- Oxygen will have a negative charge before a positive charge because it needs only two electrons to have a stable valence level. For example, Oxygen will take the electrons from two Hydrogen atoms and make H20.
What is the formlua for ozone reacting to form oxygen?
The formula for ozone reacting to form oxygen is O3+O= 2O2
