What is the number of valence electrons for H2S?
H:S:H : counts for two electrons that form a bond. ***There are also two electrons (or one bond) above Sulfur and below.All in all, sulfur possess 6 valence electrons while each hydrogen has one valence electron thus, satisfying the octet rule.
Which sum gives the total number of electrons in electron configuration?
The sum from the exponents of the blocks.For instance,If We take the electron configuration of Sulfur (S) which is:1s22s22p63s23p4The total number of electrons i going to be 2 + 2 + 6 +2 + 4, which gives 16.
Cross and dot structure of chcl3?
C is the central atom. Carbon is single bonded to H and Cl and double bonded to O. Three lone pairs of electrons on Cl and two lone pairs on O. H-C=O:: l :Cl:: In CHClO there are 18 valence electrons that can be found by looking at their Group A# (4=carbon, 1=Hydrogen,7=Chlorine, 6=Oxygen) Each loan pair counts as 2 and each bond counts as 2, so when the equation is completed, count up how many electrons to make sure it equals how many valence electrons for all the atoms (18). _____________________________________________________________ The following original solution is incorrect because Hydrogen can not make more than one bond and can not exceed 2 electrons, EVER. Also for future notes, Chlorine can not make more than one bond either. Furthermore, no atom can exceed 8 electrons due to the octet rule. _________________________________________ The central atom is C making the structure look like :O: .. H-C-Cl: '' The central atom is C making the structure look like :O: .. H-C-Cl: '' The original solution is correct, the formatting was just messed up. Cl bonds to carbon instead of H like the formatting makes it look like. Carbon is in the middle with single bond between it and Cl and H. There is a double bond between C and O. H has no unbonded electrons (it only needs two and gets both from the bond). Cl gets two electrons from the bond and has three unbonded electron pairs. O gets four electrons from its double bond and has two unbonded electron pairs. Carbon gets all its electrons from its bonds.
How do atoms fill their outer energy cells?
There are several ways: First, the atom can from a covalent bond with another atom. This means that the two atoms "share" some of their electrons, and the electrons "count" towards the shell of both atoms. For instance, hydrogen, which has 1 electron and needs two to fill its shell, could share an electron pair with chlorine, which has 7 electrons and needs 8 to fill its shell, thus giving both atoms full outer shells Second, the atom could become a negative ion. This entails it pulling an electron off another atom and into its own shell. This is most common when atoms need only one or two electrons to fill their shell, giving us -1 and -2 ions (an electron counts as -1), though higher numbers are not impossible. Note also that since the atom that got they electron has a negative charge and the atom that lost it now has a positive charge, they tend to stick together in an ionic bond.
What are elements made out of?
There are three types of particle you will find inside an atom; the proton, the neutron, and the electron. Of these, the proton and neutron each have mass '1', and the electrons mass is so small, we usually ignore it (about 1/1836, if you were wondering). Of these particles, the electron and the proton are both charged. The proton has a positive charge, and the electron has a negative charge. This is what keeps the electrons close, and this charge allows atoms to bond together to form molecules. The protons and neutrons form a stable nucleus, and the electrons orbit around them.
When are proton counts and electron counts not equal?
Ions have an imbalance of charge, with either an excess or shortage of electrons.

How can you determined the number of valance electrons by looking at the periodic table?
Elements are located on the periodic table based off of their atomic number, but the vertical columns they are in (groups) show how many valence electrons they have. If an element were in Group 3 of the periodic table, it would have 3 valence electrons, and so on. This doesn't apply to the Transition Metals, so one should skip straight to Group 14, where the elements all have 4 valence electrons. Group 15 has 5, Group 16, 6, etc. The one exception to this is Helium, which is in Group 18 but only has 2.
How do you count the electrons in a Lewis dot structure?
Count the electrons in the following way: -- each lone pair counts as 2 electrons -- each single bond counts as 2 electrons -- each double bound counts as 4 electrons -- each triple bond counts as 6 electons. -- if it an ion with a positive charge, subtract 1 electron for each charge from the total (after counting all the bonds and lone pairs) -- if it an ion with a negative charge, add 1 electron for each charge to the total (after counting all the bonds and lone pairs) Add up all the contributions for the total number of electrons!

What is static electricity in terms of movement of electrons?
Here electrons get migrated from one region to the other. Here no contiuous flow of electrons. As electrons get migrated to one region, then negative potential created would oppose further migration of electrons and hence a negativ potential is created. This is what we call CHARGED. A capacitor is a device to store electric charges by following the phenomenon of electrostatic induction.
Does a 401k loan count against my debt to income ratio?
Yes, a 401k loan typically counts as debt in your debt-to-income ratio calculation.

What exactly counts towards the calculation of the major GPA?
The major GPA includes only the grades earned in courses that are specifically required for a student's major or concentration. Elective courses or general education requirements typically do not count towards the major GPA calculation.
