When a chlorine atom gains an electron it fills its valence shell forming a negative chloride what?
The chloride ion is an anion (Cl-).
What is the outer-most shell of an atom called?
valence shell
Why is helium placed in group 8 if it has two valence electrons?
Since 2 electrons fills it's outer shell it is considered an inert gas.
What happens if the outermost electron shell is empty?
the shell would never be empty, there would be another shell under it and it would have all of its valence electrons
How do you find valence shell?
The valence shell is the outermost shell of the atom. For example, hydrogen (which is located on Period 1) has only one shell and it is its valence shell. Another example, bromine (which is located on Period 4) has four electron shells, and its fourth shell (counting away from the nucleus) is its valence shell containing seven electrons.
Does aluminum have three electrons in its valence shell yes or no?
Yes, aluminum has 3 valence electrons.
How many electrons will be in the valence shell of an aluminum atom?
there are 3 valence electrons in the atom of aluminum
Which of the following has three electrons in its valence shell carbon aluminum sodium calcium?
Aluminum
What are the number of outer-shell electrons in one atom of aluminum?
Aluminum has 3 valence electrons.
Does aluminum three electrons in its valence shell yes or no?
Yes...along with Boron
When a chlorine atom gains an electron it fills its valence shell forming a negative chloride what?
The chloride ion is an anion (Cl-).
What is the number of electrons in the valence shell of an atom of aluminum in the ground state?
2 valence electrons are in an aluminum atom in the ground state.
Why does oxygen have a subscript of 3 in aluminum oxide?
Aluminum loses three electrons to have a full valence shell. Oxygen gains two electrons to have a full valence shell. Aluminum Oxide is shown as Al2O3 because there are three oxygen atoms with a total of 6 gained electrons. Two Aluminum atoms lose 6 electrons and three Oxygen atoms gain six. This is the balance between aluminum and oxygen.
What happens when a chlorine atom gains an electron in its valence shell?
It becomes an ion.
What happens when atoms of elements combine to form compounds?
It's valence shell (outermost shell of atom) is full and stable.
How many valence shell are in Yb?
One valence shell
What shell is the valence shell?
Krypton is a noble gas; it has 8 electrons in its valence shell.
