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
loses 2 electrons to achieve a noble gas configuration
Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration. You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.
in order to attain the nearest noble gas configuration.
Yes, the outermost energy level of the atoms of the noble gases are filled, meaning that they have the maximum number of electrons. This is why noble gases are stable and unreactive. The atoms of reactive elements share or transfer electrons in order to fill their outermost energy levels, making them stable like the noble gases.
Boron must give up 3 electrons in order to achieve a noble-gas electron configuration.

nitrogen has 5 valence electrons. It should gain 3 electrons to achieve a noble gas configuration.
3
Nitrogen has to gain three electrons
it has to gain 3
2 electrons as barium has 56 electrons so it will lose two electrons to reach the electronic structure of the nearest noble gas which is xenon 54 electrons
Silver needs 7 more electrons to reach a "pseudo-noble gas" configuration.
One
Sort of. Lithium loses one electron in order to achieve the noble gas configuration of helium, which has only two valence electrons in its 1s sublevel. The octet rule refers to the fact that atoms share or transfer electrons in order to achieve a noble gas configuration with eight valence electrons, called an octet. Helium is an exception to the rule.
carbon has to gain or lose 4 electrons to gain noble gas configuration.
in order to attain the nearest noble gas configuration.
