What is the loss or gain of an electron?
electrons... and thus one unit of negative charge....
What is fomed when one atom takes an electron from another atom?
When electrons move from one atom to another, they change the charge of the atoms. If you remove one electron that atom becomes 1+ charged because a negative was taken away, making it more positive than negative. The atom that recieves an electron becomes 1- charged because you added a negative, making the atom more negative than positive.
Why do poles on a magnet attract and repel?
Poles on a magnet attract or repel because of the way the electrons line up. The electrons in the valence shells tend to line up on one side of the nucleus. The electrons have a negative charge and the nucleus has a positive charge. The negative charges in one magnet repel the negative charges in another magnet but attract the positive charges in another magnet.
Can pregnancy test be negative one day and be positive two days later?
Yes. It is always better to go an consult a doctor if you are in doubt.
What are the Negative and positive effects of Solar Energy?
One Positive effect of a solar panel is that 1. There is no pollution 2. It's very effective for when in a sunny location Negative effects: 1. Very expensive and not easy to install 2. Not very effective when in a place that have little or no sunshine at all I hope this is of use ^^
What is a positive electrode?
A positive electrode is a cathode. A negative electrode is an anode.An anode is positively charged, while a cathode is negatively charged.
When the switch is closed which electrode will attract the sodium ion?
Negative electrode Cathode One on the right
What element is in center electron post of a battery?
We find carbon or graphite as the center electrode of a zinc-carbon battery. It's the "common" battery we use in lots of stuff (but not an alkaline battery). That center electrode is the positive one, and the zinc makes up the outer or negative electrode in this battery. In an alkaline battery, manganese dioxide is the center, or the cathode (positive electrode). Powdered zinc will be found as the outer or negative electrode (anode).
What is an electrobe that has a positive charge?
Assuming this is a misspelling of "electrode" ... Electrochemistry can be confusing, because the answer depends on the type of device! In a galvanic cell (or discharging battery), the positively charged electrode is the cathode. However, in an electrolytic cell (or recharging battery), the positively charged electrode is the anode. The easiest way to keep this straight is to remember that the cathode is the one the cations (positively charged ions) migrate towards, and the anode is the one the anions (negatively charged ions) migrate towards.
Which electrode will be negative if you connect magnesium and lead in one cell?
the magnesium would be negative
What charge must the food dyes have had in order to move through the electrophoresis chamber?
In an electrophoresis chamber, food dyes must carry a net charge that allows them to migrate towards the electrode of opposite charge. Typically, if the chamber is set up with a positive electrode (anode) at one end and a negative electrode (cathode) at the other, the dyes must be negatively charged to move toward the positive electrode. Conversely, if the dyes are positively charged, they would migrate towards the negative electrode. The specific charge of the dyes can depend on the pH of the medium and the chemical properties of the dyes themselves.
In silver plating one electrode in solution is made of pure silver The other electrode is the?
a) conducting solution b) negative battery terminal c) positive battery terminal d) object to be plated e) electrical connecting wire
Rules for adding integers?
When you add: a negative and a negative: you get a negative a positive and a positive: you get a positive a positive and a negative or a negative and a positive: Subtract the addend with the smaller value from the greater one. If the greater one is positive, your answer will be positive. If the greater addend is negative, your answer will be negative.
How do you add positive and negative fractions?
-- Remember which one was positive and which was negative, then forget about the signs.-- Write down the one that was positive-- Subtract from it the one that was negative(Notice that if the negative one was bigger, then the answer will be negative.)
What is the positive and negative advantages?
Positive one are helpful, negative one are unhelpful
When you mutiply a positive number by a negative one what is the sign of the answer?
The answer will ALWAYS be negative positive x negative=negative and vice versa positive x positive= positive
When you multiply a positive number by a negative by a negative one what is the sign of the answer?
A negative times a positive is a negative and that negative times a negative would = a positive. So the answer would be a positive number. *<:)
