How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
Why do valence electrons determine the reactivity of an atom?
The valence electrons are the outermost electrons. In an atom, its lower energy levels have been filled and are therefore stable. But, except for the noble gases, the valence energy level is not filled, and therefore not stable. So atoms must undergo chemical reactions in order to fill their valence shells and become stable. They can do this by sharing electrons, transferring electrons, or by forming a sea of electrons shared by all the atoms.
How many valence electrons does helium need to gain to have a filled outermost energy level?
0 It already is full
The element with 4 energy levels and 4 valence electrons is Titanium right?
That is correct. Titanium has 22 electrons, and its highest full orbital is 4s and the 3d is partially filled with 2 electrons. So Titanium is 1s22s22p63s23p64s23d2
How many electrons does carbon need to have the outermost energy shell filled?
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
How many valence electrons does heluim need to have a filled outermost energy level?
Helium only needs two electrons to have a filled outermost energy level.
The electrons that occupy the outermost filled shell are called?
Outer energy level electrons, or valence electron.
What is an element with 7 valence electrons and 4 energy levels?
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
What are elements with 1 or 2 electrons in the outer energy level called?
Group 1: have 1 valence electrons (half filled s orbital) Group 2: have 2 valence electrons (completely filled s orbital)

0 It already is full
How many valence electrons does helium need to have filled outermost energy level?
helium has 2 valence electrons (in s orbital) and has complete s orbital. So it does not need to gain or lose more electrons to be stable.
The element with 4 energy levels and 4 valence electrons is Titanium right?
That is correct. Titanium has 22 electrons, and its highest full orbital is 4s and the 3d is partially filled with 2 electrons. So Titanium is 1s22s22p63s23p64s23d2
What two atoms will have their outer energy level filled with two electrons?
Helium and neon will have their outer energy level filled with two electrons. Helium has 2 electrons in its only energy level, while neon has 8 electrons in its second energy level.
What is the noble gases that have a full number of valence electrons?
All noble gases (helium, neon, argon, krypton, xenon and radon) have completely filled valence shell / valence energy level / valence orbitals.
How many electrons does carbon need to have the outermost energy shell filled?
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
What is neon's valence shell?
Neon is a noble gas, thus It has a full valence shell of eight electrons.
