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
HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.
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).
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.
A molecule of crotononitrile (C4H5N) has 9 valence electrons. This is calculated by adding the valence electrons of each element: carbon (4), hydrogen (5), and nitrogen (1).
No. Carbon has 4 electrons in its outer shell (valence shell).
HCN, hydrogen cyanide, has a total of 10 valence electrons. Hydrogen contributes 1 valence electron, carbon contributes 4 valence electrons, and nitrogen contributes 5 valence electrons.
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).
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.
all carbon atoms have 4 valence electrons. 4 hydrogen atoms can bond to a single carbon. That would be methane.
In CH4O, there are 14 valence electrons: 4 from carbon, 1 from hydrogen, and 6 from oxygen.
Methyl fluoride, CH3F, has a total of 14 valence electrons. Carbon contributes 4 valence electrons, each hydrogen contributes 1 valence electron, and fluorine contributes 7 valence electrons.
4 electrons
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.
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.
nitrogen has 5 valence electrons. carbon has 4 valence electrons.
A molecule of crotononitrile (C4H5N) has 9 valence electrons. This is calculated by adding the valence electrons of each element: carbon (4), hydrogen (5), and nitrogen (1).
Carbon (C) has 4 valence electrons, hydrogen (H) has 1, fluorine (F) has 7, and chlorine (Cl) has 7. Therefore, CHF2Cl has 24 valence electrons in total.
