What is shared when elements combine to form compounds?
Electrons are shared when elements combine to form molecules.
Why will an alkali metal often combine with a halogen nonmetal to form a compound?
Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.
What happens to the valence electrons of magnesium oxide?
Mg donated two valence electrons to O.
What is valency of aluminium in aluminium oxide?
AL2O3: Aluminum has three valence electrons to give, the oxygen atoms can accept 2 valence electrons. With the compound being made of 3 oxygen atoms (which have 6 valence atoms individually) they accept 2 of the aluminums valence electrons. In electrical practice, this compound is an insulator. One atom or compound having 6-8 valence electrons is electrical insulator.
What happens to the valence electrons when new compounds are formed?
This is a somewhat broad question because there are many different kinds of compounds, and there are a variety of things that happen to valence electrons depending upon what kind of compound is formed, but in general, any given atom has 3 options when forming a compound: it can give up one or more electrons, acquire one or more electrons, or share one or more electrons.
What is shared when elements combine to form compounds?
Electrons are shared when elements combine to form molecules.
Does the valence of an atom tell it what it can and cannot combine?
The valence indicate the type of a possible compound.
What happens to valence electrons as you move across the row?
The number of valence electrons increases.
Why will an alkali metal often combine with a halogen nonmetal to form a compound?
Well, the "happy" number in chemistry is eight. And alkali metals have one valence electron while halogens have seven so when they combine, the combination has eight valence electrons. This means it is full.
What is the compound formed between Ba and S?
Ba is a group 2 elements with 2 valence electrons. S is a group 16 element (or oxygen family) and has 6 valence electrons. Ba gives 2 of it's valence electrons to S giving both atoms an octet. They combine in an ionic compound in 1:1 proportions. The formula is BaS and it's called barium sulphate
What happens to the valence electrons of magnesium oxide?
Mg donated two valence electrons to O.
How many valence electrons can combine with other elements?
all the electrons that are available in outermost shell
How many valence electrons does NaCl have?
electrons in Na2O
The valence electrons are?
Valence electrons are: In chemistry, those electrons found in orbits farthest from the nucleus of the atom. These electrons determine the way in which the atom will combine with other atoms, and thus determine its chemical properties.
What is valency of aluminium in aluminium oxide?
AL2O3: Aluminum has three valence electrons to give, the oxygen atoms can accept 2 valence electrons. With the compound being made of 3 oxygen atoms (which have 6 valence atoms individually) they accept 2 of the aluminums valence electrons. In electrical practice, this compound is an insulator. One atom or compound having 6-8 valence electrons is electrical insulator.
When covalent bonds form what happens to electrons?
the valence electrons are shared.
What happens to the valence electrons when new compounds are formed in covelant bonding?
valence electrons are shared in covalent bonding
