Number of valence electrons in two hydrogen atoms?
Two. One hydrogen atom has one valence electron, so two hydrogen atoms will have two valence electrons :)
The number of valence electrons in cyclopentadiene C5H6 is?
The number of valence electrons in cyclopentadiene C5H6 is 54. Carbon has 4 valence electrons and hydrogen has 1, giving a total of 30 for carbon atoms and 24 for hydrogen atoms.
how many hydrogen atoms must be bond to silicon to give it an octet of valence electrons?
Silicone has 4 valence electros so it would need 4 hydrogen atoms to give itself an octet of valence electrons.
How many Valence electrons are on bhf2?
Boron has 3 valence electrons, and each hydrogen has 1 valence electron. There are two hydrogen atoms in BH2F, so BH2F overall has 3 + 2 = 5 valence electrons.
How many valence electrons does acetylene have?
Acetylene (C2H2) has 2 valence electrons for each carbon atom and 1 valence electron for the hydrogen atoms. Therefore, acetylene has a total of 10 valence electrons (4 from carbon and 6 from hydrogen).
How many valence electrons in H2 atom?
H2 is not an atom, it is a diatomic molecule. Each hydrogen atom has 1 valence electron. When two hydrogen atoms covalently bond to form an H2 molecule, there are two valence electrons being shared by the two atoms.
How many valence electrons do atoms in period 1 have?
Hydrogen has 1 valence electron, whereas helium has 2 valence electrons.
How many valence electrons does H2O2have?
H2O2 is a compound, and the concept of "valence electrons" applies to atoms but not to compounds. If the question is or should be intended to be, "How many valence electrons did the atoms in one formula unit of H2O2 have before they reacted to form the compound?", the answer is one from each hydrogen atoms and six from each oxygen atom, for a total of 14.
What is the number of valence electrons in CH2O?
The number of valence electrons in CH2O is 14. Carbon contributes 4, each of the two hydrogen atoms contributes 1, and oxygen contributes 6 valence electrons.
What kind of bonding is hydrogen gas occurs when two valence electrons are shared between the Hydrogen atoms?
covalent
How many valence electrons does CH3CO-OH have?
CH3CO-OH (acetic acid) has 10 valence electrons. The carbon atom contributes 4 valence electrons, each hydrogen atom contributes 1 valence electron, and the oxygen atom contributes 6 valence electrons.
What Carbon has four valence electrons How many hydrogen atoms can bond to a single carbon atom?
all carbon atoms have 4 valence electrons. 4 hydrogen atoms can bond to a single carbon. That would be methane.
