How do you write the charge of an ion?
find the difference between the number of electrons and protons, and then find whether protons(+) or electrons(-) are more abundant. if the difference was 2, for example, and there were (2) more protons than electrons, the charge would be written as: chemical symbol 2+
How do you draw the Lewis structure for 3CO2?
:CO draw 2 of the electrons to the left of carbon then 2 to the right and then draw 2 electrons of oxygen to its left and then the other 4 around the other sides of oxygen and draw a circle around the 2 electrons shared with carbon and the 6 existing electrons of oxygen then draw a circle around the 4 electrons carbon has and the 2 it shares with oxygen and after you've done all that, draw a bracket around the molecule and write -2 in superscript signifying that its net charge is -2
If you have an ion that is a transition metal you need to write the charge as what?
The charge it's written in parentheses with Roman numerals: Fe(II).
What do you right on the right side of a postcard?
You write on the left side of the postcard and you write the address of the person you are sending the postcard to on the right side.
How do you find out how many valence electrons are in a molecule?
The valence electrons are the electrons in the last shell or energy level of an atom. They do show a repeating or periodic pattern. The valence electrons increase in number as you go across a period. Then when you start the new period, the number drops back down to one and starts increasing again.1A2A3B4B5B6B7B------8B------1A2A3A4A5A6A7A8AH1He2*Li1Be2B3C4N5O6F7Ne8Na1Ar8K1Sc3Ti4V5Cr6Mn7Fe8Co8Ni8Cu1Zn2Kr8For example, when you go across the table from carbon to nitrogen to oxygen, the number of valence electrons increases from 4 to 5 to 6. As we go from fluorine to neon to sodium, the number of valence electrons increases from 7 to 8 and then drops down to 1 when we start the new period with sodium. Within a group--starting with carbon and going down to silicon and germanium--the number of valence electrons stays the same.Every electron that's a valence electron in an atom is also a valence electron in a molecule formed by that atom. For example, an atom of carbon has 4 valence electrons. That means the carbon atom in carbon dioxide CO2 must contribute 4 valence electrons to the carbon dioxide molecule.An electron that is added to or subtracted from a molecule to make a polyatomic ion is assumed to be a valence electron.These facts let you count the valence electrons in the N2[CH3]42+ion in two steps:Add up the valence electrons from each atom that forms the molecule.Sometimes it helps to write the simplest form of the chemical formula vertically while you do this:N22 x 5 = 10( 2 nitrogen atoms, each with 5 valence electrons )C44 x 4 =16( 4 carbon atoms, each with 4 valence electrons )H1212 x 1 = 12( 12 hydrogen atoms, each with 1 valence electron )38total valence electrons from the atomsAdd or subtract valence electrons to account for the charge on the molecule.For example, if the molecule has a charge of -1, add 1 valence electron. If the molecule has a charge of -2, add 2 valence electrons. On the other hand, if the molecule has a charge of +1 , subtract 1 valence electron, and if the molecule has a charge of +2, subtract 2 valence electrons.In this case, since the N2[CH3]42+ion has a charge of +2 we need to subtract 2 valence electrons , for a new total of 36 valence electrons.
What is the relation with charge on electrons to electron flow in a circuit?
Not entirely sure what the point of the question is, but here are two of the relations between the charge of the electron and electron flow in a circuit; I hope this helps.1. The electron has a negative charge. This is an accident of history; there's really nothing fundamentally "negative" about the electron charge, it's just that some some particles have one kind of charge and others have an opposite one, and the the sign of the charge was assigned before electrons had really been discovered. The choice was arbitrary and could have gone either way, but electrons just happened to end up negative. You can blame Ben Franklin for it. But I digress.Electric current is defined as flowing from positive to negative. If the mobile charge carriers are positively charged, then they are flowing in the same direction as the current. But if the mobile charge carriers are negative - like electrons, which are the carriers in metals - then the carriers are flowing in the opposite direction from the current. In other words, the electrons flow "backwards" because they are negative, because Ben Franklin just happened to write '+' and '-' in the "wrong" places (though he couldn't possibly have known.)2. The electron charge is -1.6×10-19 Coulombs. To put that another way, one Coulomb is about 6.24×1018 electrons worth of charge. Since one Ampere is the flow of one Coulomb of charge per second, it is also a flow rate of 6.24×1018 electrons per second. That's more than six billion billion electrons each second for each Ampere!
write a simple word equation that shows you can figure out the charge of an ion given its numbers of electrons and protons?
If there are more electrons than protons, then the ion charge is negative. If there are more protons than elections, then the ion charge is positive.
How do you write the charge of an ion?
find the difference between the number of electrons and protons, and then find whether protons(+) or electrons(-) are more abundant. if the difference was 2, for example, and there were (2) more protons than electrons, the charge would be written as: chemical symbol 2+
For calcium ca write the numbers of electrons it must gain or lose to have 8 vlance electrons then calculate the charge of the ion that would form?
Ca must lose 2 electrons to have a complete 3n shell, which has 8 valence electrons. The ion would have a charge of 2+: Ca^2+.
What are the semiconductors in the periodic table?
Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to make impure.
How do you draw Lewis dot diagram of Br with a negative charge?
Br- ion will have 8 valence electrons. So to write the Lewis structure, write the symbol Br, with 8 dots around it. Each dot will correspond to one electron.
Is the correct ionic form for carbon c?
no i believe it has something to do with the group its in on the periodic table. its in group 6a so look up how to write the formula from there and its ionic charge is +4 or a -4 charge because it has four electrons in it's outermost electron level
What are the 3 subatomic particles -?
Protons (positive), Neutrons (no charge), and Electrons (negative). The protons and neutrons are both found in the nucleus of the atom, which is at the center. The electrons are in the electron cloud surrounding the nucleus.
How do you draw the Lewis structure for 3CO2?
:CO draw 2 of the electrons to the left of carbon then 2 to the right and then draw 2 electrons of oxygen to its left and then the other 4 around the other sides of oxygen and draw a circle around the 2 electrons shared with carbon and the 6 existing electrons of oxygen then draw a circle around the 4 electrons carbon has and the 2 it shares with oxygen and after you've done all that, draw a bracket around the molecule and write -2 in superscript signifying that its net charge is -2
