What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
A stable atom has equal numbers of?
Having an equal number of anything does not make an atom stable.
Is hydride ion more stable or less stable than H-atom?
hydried is more stable than H-atom
Is the Atomic number of 7 a stable atom?
yes it is stable
An atom is stable when its outermost orbit is?
It is stable when filled with electrons.
Is chlorine atom stable?
Yes, Chlorine atom is stable
What is an atom stable?
An atom is stable if it does not undergo decay.
What is a partially filled outer electron level makes with?
A completley filled out electron level makes the atom stable
What causes an atom to be stable?
An atom becomes stable by gaining or loosing electrons.
Can a stable atom have an orbital which has three electrons?
Yes, if the orbital is the outermost one that includes the valence electrons. Aluminum, for example, is such an atom, as is boron.
A stable atom has equal numbers of?
Having an equal number of anything does not make an atom stable.
Is hydride ion more stable or less stable than H-atom?
hydried is more stable than H-atom
Is the Atomic number of 7 a stable atom?
yes it is stable
An atom is stable when its outermost orbit is?
It is stable when filled with electrons.
How many electrons does a stable sodium atom have?
A stable sodium atom has 11 electrons.
How does a atom become stable?
When the atom has 8 valence electrons.
Would an atom with 3 electrons in level M tend to gain or lose electrons?
That depends on the element. Any such atom with more than four protons will gain electrons to become electrically neutral. If that atoms has four protons (beryllium) then it will be able to form a stable ion with two electrons. If it is left with three electrons it will either gain an electron to form a neutral atom or, if in the presence of an oxidizing substance, lose an electron to form an ion. If the atom has three protons (lithium) it will form a stable, neutral atom with three electrons but will lose one electron when it reacts to form a stable ion. If that atom has two protons (helium) then it will only be stable with two electrons and will gain or lose electrons accordingly to maintain that number. If the atom has one proton (hydrogen) then it will tend to share electrons rather than gaining or losing them. It forms a neutral atom with one electron but can form an ion with two. It has no stable configuration with three electrons.
