What element is most reactive an en element with 7 valence electrons or an element with 8 valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
Does the valence shell of electrons determine how one atom bonds to another atom to make a molecule?
No, valence electrons are the electrons in the outermost energy level of an atom. A molecule is the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
What is a colvant bond?
There are three different types of bonds of electronegavitity.Electronegavitity is how much an element is attracting another eletron. Another way of saying it is how much an element want electrons from other elements.1 type of bond is ionic bond: it is an attraction between opposite charged ions.2 type of bond is covalent bond: bonds that shares electrons so elements can get its full shell and be stable (happy!).(most elements want 8 total valence electrons while in rare cases element like H wants 2 valence eletrons)3 type of bond is Metallic bond: is a bonding between metals.
When atoms share valence electrons to form a chemical bond what kind of bond is formed?
Chemical bonds don't form electrons; an element has valance electrons. Covalent bonds are formed when elements share their valance electrons. An element wants to have 8 valance electrons. That is when it is an "happy atom". For example, carbon has has four valance electons, so it typically bonds with hydrogen and oxygen to get those four valance 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.
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.

How many valence electrons will aluminum have to lose to be happy?
To be very stable it will have 8. Since a common Aluminum atom has 3, it will lose the 3.
Does the valence shell of electrons determine how one atom bonds to another atom to make a molecule?
No, valence electrons are the electrons in the outermost energy level of an atom. A molecule is the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.
How many valence electrons are in a full outer shell?
8 - called valence electrons. it doesn't matter what energy level or orbital shape. a "happy atom" has 8 valence electrons
Do valence electrons affect the reactivity of an element?
atoms are most stable when they have filled the outer shell of electrons which normally holds a max of 8. so if an atom has 1 electron in its outer layer getting rid of it will give him stability, in much the same way having 7 electrons will mean gaining one electron will give it stability. now lets say the two meet, they react with each other and everybody is happy. It is thought than when two elements react, they are trying to acheive a "perfect" electronic configuration (i.e. have a full outer shell). The more electrons needs to lose/gain before acheiving this stability determines its reactivity.
Why are the atoms of the noble gases stable?
The atom is stable when its outermost shell is full because of the fact that it is "happy" and does not want to bond with other atoms.In other words, it doesnt have room for any more bonds with other atoms.

What is true about the electrons in a sulfur ion?
They have a charge of e. They are on orbitals. They are localized. The valence electrons are happy because they are in a circle of 8 good electron friends.
Why don't noble gases chemically combine with any other elements?
they do not exist as molecules because they are noble gasses; as in they already have 8 valence electrons and therefore do not need anymore to have a full outershell. they rarely ever bond to anything because they are already stable and do not need to bond to have 8 valence electrons as most elements do when they become ions.
Why is there 118 electrons in the element chromium?
Who told you that chromium had 118 electrons - there are only 24. Check it out with Wikipedia. There you find the element that really has 118 electrons. Happy hunting. (PS - Hint - there is a very close correlation between the number of electrons and the atomic number of the element.)
Is chlorine stable?
Yes, chlorine is stable. Chlorine is a halogen, which therefore has 7 electrons on its most outer orbit; making this orbit one electron away from being full. When an element has a full outer orbit, it is "happy" and does not combine or react with other elements. Chlorine has an almost full outer layer, therefore, it is stable.
