They can do either - and they will. This is the fundamental mechanism behind the science we know as chemistry. Or Yes, they do. Some want to borrow some and some want to loan some out. This is the fundamental mechanism behind the science we know as chemistry.

Is the krypton element stable or unstable?
no it is not stable bcoz if an atom needs to be stable it needs to have 8 electrons in the valency (outermost) shell,where as a krypton has only 2 in its valency electron.
Does a H ion have two electrons?
No, the former answer (striked through below this) is very wrong!Hydrogen (elemental H atom) contains only 1 (one!) electron (1s1) and since a H ion (H+) has lost that one to become stable, this H+ ion has no (zero!) electrons at all.Only the very rare and exceptional, negatively charged hydride ion H- ion contains two electrons (1s2 configuration, not favoured, not enough electronegativity)Yes. A Hydrogen atom "wants" to be stable, so it gains an electron to be iso-electronic with helium. After that, its electron configuration is 1s2. H+
How many valence electrons do Halogens have in p subshell orbitals?
Halogens have 5 electrons in their outermost p shell in their electrically balanced state. The p shell has 3 orbitals in each energy level. Halogens have 2 filled orbitals each with 2 electrons in them and one orbital with only one electron in it. In order to obtain the stable noble gas electron configuration, halogens gain one electron to completely fill the p shell on the outermost energy level. This gives halogens a charge of -1.
Why do atoms share or transfer electrons?
The number of electrons atoms donate or accept or share has to do with the octet rule. The octet rule is a rule of thumb that reflectfalses thethis is not ture increase stability of an atom when it has a complete valence shell (which is usually 8 valence electrons). Therefore, if an electron has one less electron than is necessary to complete its outer valence shell, it will accept an extra electron. The halides, such as fluorine, chlorine, bromine and iodine are all missing one electron to reach a stable octet (the noble gas configuration), and all accept one electron. The alkali metals, such as lithium, sodium, potassium and rubidium all lose one electron because they have one more electron than the noble gas configuration.See the Related Questions for more information about counting valence electrons and the octet rule.
Which element tends to gain one electron?
Boron, Krypton,Neon, and Radon Krypton, Neon and Radon do not gain electrons. Because an atom wants to have eight electrons in their valence shell or their outermost shell, and Krypto, Neon and Radon are Noble Gases which already have eight in their valence shells, so they don't lose or gain electrons. And as for Boron it want's to gain 5 electrons because it only has three in its valence shell.
Atoms gain or lose electrons to achieve?
A stable electron configuration.
What does oxygen need to do in order to to achieve a stable electron configuration?
Oxygen atoms need to share or gain two electrons in order to achieve a stable electron configuration.
How do ionic compound obtain a stable electron configuration?
They achieve stable configuration by sharing their electrons in their outermost shell.
How many electrons are needed to be gained or lost in aluminium to achieve stable electron configuration?
Only three electrons.
Describe 1 way an element can achieve a stable electron configuration?
. Through the transfer of electrons between atoms
Explain what atoms are trying to achieve in there electron shells when they bond with each outher?
Atoms are trying achieve a stable electronic configuration i.e., stable arrangement of electrons in their electron shells. All configurations are not stable. Mostly stable configuration is attained by forming an octet of electrons in outer most shell. Sometimes octet rule is violated also.
Have two valence electrons and get to a stable electron configuration by using two electrons?
an element with 2 valence electrons can obtain a stable electron configuration by "kicking out" two electrons to have the same electron config as the noble gas in the previous period
What is the number of electrons that Br lost in forming?
Br typically gains one electron to achieve a stable electron configuration, rather than losing electrons.
Why is the ionisation energy of Nitrogen higher than Beryllium?
Beryllium is a metal. It has 2 valance electrons (in the outer shell), and therefore it tends to lose those electrons in order to achieve a stable electron configuration, which in the case of beryllium is also 2 electrons, but in the inner shell. Nitrogen is a nonmetal, with 5 valence electrons, and it tends to acquire more electrons in order to reach a stable electron configuration of 8. Less energy is need to lose electrons when the result is going to be a stable electron configuration.
What is the electron configuration on a stable ion of aluminum?
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
Do Ionic share or transfer electrons?
To achieve octet configuration (stable)
