  2. How do you count the valence electrons of an atom? - Answers

    www.answers.com/chemistry/How_do_you_count_the_valence_electrons_of_an_atom

    16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons) To count the valence electrons of an atom, you look at the group number of the element on the Periodic Table. For main ...

  3. How do you count valence electrons in compounds? - Answers

    www.answers.com/natural-sciences/How_do_you_count_valence_electrons_in_compounds

    Valence goes up to the group number for the first half of the d-block (2–7), then climbs back down (6–2) for the end. The bottom rows approach the extremes of bond number (8) and are more ...

    In the calculation of valence electron counts using the 18-electron rule, phosphine (PH3) contributes 5 valence electrons. Since each hydrogen atom contributes 1 electron, the total valence ...

  5. How many valence electrons does CH4? - Answers

    www.answers.com/chemistry/How_many_valence_electrons_does_CH4

    CH4 (methane) has 4 valence electrons because carbon (C) has 4 valence electrons and each hydrogen (H) contributes one valence electron. .. There are no valence electrons.It is non polar. In CH4 ...

  6. How many valence electrons does ICl4 have? - Answers

    www.answers.com/chemistry/How_many_valence_electrons_does_ICl4_have

    ICl4- has 36 valence electrons. Each chlorine contributes 7 valence electrons, and iodine contributes 7 valence electrons but also has a negative charge, adding an extra electron. Each atom ...

  7. What do covalent bonds do to valence electrons? - Answers

    www.answers.com/chemistry/What_do_covalent_bonds_do_to_valence_electrons

    Covalent bonds are when two or more atoms share electrons to receive perfect valence electron shells. So for example, H20, two hydrogen, with one valence electron, and one oxygen with six to form ...

    How many valence electrons does thulium? Thulium has an electronic configuration of [Xe] 4f136s2 You could count either 2 or 15. The concept of valence electrons is almost meaningless when applied ...

  9. How many valence electrons are in iridium? - Answers

    www.answers.com/chemistry/How_many_valence_electrons_are_in_iridium

    Best Answer. 2 valence electrons are in iridium because iridium is a transition metal. Most transitions metal would have 2 valence electrons because the group before the transition metals are the ...

  10. How many valence electrons does group 18 elements have?

    www.answers.com/earth-science/How_many_valence_electrons_does_group_18...

    It has 8. It just depends on the group, like group 1 has 1 valence electron, and so on, but it doesn't count for metals, so when you get to group 2, skip the metals and go to group 13 which has 13 ...
