What is an outer shell of an element?
The outer shell is the valence electrons and they are very loosely bound to the nucleus - less force by the nucleus on the valence electrons, so valence shell's electrons are exchanged first in any reaction.Valence
Why is krypton unreactive?
Krypton is a noble gas and has a particularly stable electronic configuration. That's why it may be very unreactive.
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
Which chemical family is composed of elements that have full valence shells?
The noble gases are the chemical family composed of elements that have full valence shells. These elements include helium, neon, argon, krypton, xenon, and radon. Due to their full valence shells, noble gases are known for their stability and lack of reactivity with other elements. This stability is attributed to the fact that their outermost energy levels are completely filled with electrons.
Would beryllium tend to lose two electrons or gain six when forming bonds?
Beryllium would tend to lose its two electrons when forming a bond because it is easier to lose its two valence electrons rather than gain an additional five in order to obtain a full outer shell.
How many more valence electrons does oxygen need to have a full outer?
Oxygen needs 2 more valence electrons to have a full outer shell. Oxygen has 6 valence electrons, and a full outer shell for oxygen is achieved at 8 valence electrons.
How many more valence electrons does magnesium need to have a full outer valence shell?
it needs six more electrons to have a full outer valence shell.
What are atoms valence electrons?
the electrons on their outer shell, all atoms want to gain a full valence shell.

How many more valance electrons does oxygen need to have a full outer valence shell?
None. Neon is a noble gas, a category of elements that exist in nature as inert gasses. In special situations, neon can be made to react with other elements, but in ordinary conditions, neon is inert, which just means non-reactive. It's outer orbit is full--it doesn't want to give up the electrons it has, or to take any more.
What is the valence of Xenon?
Xenon has a valence of 0, as it is a noble gas and has a full outer shell of electrons.
If an atom has a stable number of electrons how can you tell?
If an atom has a stable number of electrons, it will have a full outer electron shell (valence shell). This full outer shell will typically have 2, 8, 18, or 32 electrons, depending on the period the atom is in. Atoms with full valence shells are considered stable because they are less likely to undergo chemical reactions to gain or lose electrons.
How many more valence electrons does soduim need to have a full outer valence shell?

How many valence electrons are needed to achieve a full outer shell?
It depends, most atoms need 8 total valence electrons in their outer shell (some need 2). So subtract the number they have (determined by the group that the element is in) from 8 and that is how many they need to fill their outer shell!
How many number of electrons to fill the outer shell of carbon?
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
How many valence electronss are there in Boron?
There are three valance electrons. These are the electrons in the outer shell if it is not full.
How many electrons are in the outer shell of Ar?
Argon has eight valence (outer) shell electrons. It is a Noble Gas so its valence shell is full (Octet Rule).
