Can hydrogen fill it's outside shells with two electrons?
No. Hydrogen is extremely unreactive because it only has one valence electron.
How many valence electrons do the halogen have?
The number of electrons in the valence shell of a halogen is 7. What is probably the most significant feature of halogens is that they all are one electron short of the number of electrons required to fill their valence shells, eight. That means they will have similar chemical properties, i.e., they all are on the lookout to borrow one electron.
When is the valence shell stable?
Whenever the outside shell of the atom, or valence shell, is completely full with electrons. Ex: The noble gases are lucky enough to start out stable because they fill their outer shells.
How many electrons does antimony need to fill its valence shell?
antimony has 5 valence electrons
Elements in the same group have similar properties because they have the same?
the same number of electrons needed to fill their octet, the same number of valence electrons,
Why do elements as a family or group share similar properties?
Because they have the same number of valence electrons and need the same number of electrons to fill their valence shells
How many electrons are needed in hydrogen helium carbon and oxygen to fill their respective valence shells?
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell
Why do group one elements have similar properties?
;need the same number of electrons to fill their valece shells ;have the same number of valence electrons
Can hydrogen fill it's outside shells with two electrons?
No. Hydrogen is extremely unreactive because it only has one valence electron.
How are valence electrons differ from other electrons in an atom?
The closer the number of valence electrons is to the number required to completely fill or deplete its outer shell the more likely the atom is to react. With other electrons in an atom the shells are full and they have little if any affect on the reactivity of an atom. Valence electrons are the only electrons that are available to be shared/transferred in a bond.
How many valence electrons do the halogen have?
The number of electrons in the valence shell of a halogen is 7. What is probably the most significant feature of halogens is that they all are one electron short of the number of electrons required to fill their valence shells, eight. That means they will have similar chemical properties, i.e., they all are on the lookout to borrow one electron.
Does helium have the same amount of valence electrons as the others in its group?
No it does not, there are shells and orbitals that determines how reactive an atom is. Helium has 2 valence electrons, which fill up its entire shell, so it is like a noble gas. the other noble gasses have 8 valence electrons, which fill up their entire shell.
When is the valence shell stable?
Whenever the outside shell of the atom, or valence shell, is completely full with electrons. Ex: The noble gases are lucky enough to start out stable because they fill their outer shells.
Why nonmetals do not have free electrons which conduct electrical energy?
Because the outer shells are very close to the nucleus and the number of electrons in the outer shells are between 4-8. Therefore, they are not freed from the nucleus easily rather they look for some more electrons to fill its outer shell which is technically called as covalent bond.
How many electrons does antimony need to fill its valence shell?
antimony has 5 valence electrons
How do nonmetals fill their outer shells when forming bonds with metal?
The positive and negative are attracted
What is the number of electrons to fill fluorine?
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
