How do valence electrons of atoms behave when forming an ionic bond?
Electrons are transferred when ionic bonds are formed.
How do chemists know if ions behave independently?
Chemists know that separated ions are present in a solution is because it is an excellent conductor of electricity.
What do alkali metals behave like?
Because all alkali meals have same no of electrons (only one) in their outermost shell
What is the electron flow theory?
Voltage should be more correctly called "potential difference". It is actually the electron moving force in electricity (emf) and the potential difference is responsible for the pushing and pulling of electrons or electric current through a circuit. To produce a drift of electrons, or electric current, along a wire it is necessary that there be a difference in "pressure" or potential between the two ends of the wire. This potential difference can be produced by connecting a source of electrical potential to the ends of the wire. As I will explain later, there is an excess of electrons at the negative terminal of a battery and a deficiency of electrons at the positive terminal, due to chemical action. Then it can be seen that a potential difference is the result of the difference in the number of electrons between the terminals. The force or pressure due to a potential difference is termed e.m.f. or voltage.See: electron theory An emf also exists between two objects whenever there is a difference in the number of free electrons per unit volume of the object. If the two objects are both negative, current will flow from the more negatively charged to the less negatively charged when they are connected together. There will also be an electron flow from a less positively charged object to a more positively charged object. The electrostatic field, i.e. the strain of the electrons trying to reach a positive charge or from a more highly negative charge is emf or voltage. It is expressed in units called volts, short for voltage. A volt can be defined as the pressure required to force a current of one ampere through a resistance of one ohm. To make this easier to visualise, consider the water pressure (voltage) required to pass a litre of water (current) through a copper pipe of a certain small diameter (resistance). Also try and visualise water going through other pipes of varying diameters (smaller to larger in size). Either the water pressure required would vary or the volume delivered would vary, or both. You have just grasped the basics of ohms law, where E = voltage; I = current in amperes and R = reistance in ohms: Some examples: Chemical (batteries) e.g. dry cell 1.5V, wet cell storage about 2.1V Electromagnetic (generators) Thermal (heating junctions of dis-similar metals) Piezoelectric (mechanical vibration of certain crystals) Photoelectric (light sensitive cells)
Why aren't all atoms magnets?
While electrons behave like magnets, not all atoms are magnets. Electrons typically pair up with spins opposite each other making their fields cancel each other.
How does current electricity behave?
In a very predictable way. It follows Ohms law. Electrons do not flow instead they transfer their charge down a conductor to where they do work. Usually heating or lighting. They can excite a magnetic field and make a motor go. As a magnetic field is crossed by a conductor a current is generated.
Electrons behave like what?
Electrons behave like waves and particles this is characterised by the wave side in the Bohr model and can be diffracted yet it will collide with other particles.
Why is it that conductors and insulators of heat also seem to behave in the same way for ellectricity?
Heat Induction is also due to electrons. Heat is induced from one to another when the electrons vibrate. Now, the degree of this vibration depends on material to material.. If an electron vibrates very rapidly this means it is also free to move. Hence a good conductor of heat is also a good conductor of electricity. Hence, vice versa.
How do valence electrons of atoms behave when forming an ionic bond?
Electrons are transferred when ionic bonds are formed.
Why do electrons behave like magnets?
Electrons move in orbit and thus produce a magnetic field like a electromagnet.
An electron model is a good approximation of?
how electrons behave in their orbitals
How do you determine if a transistor is open?
1...The base emitter junction should behave as a diode, conducting when a positive voltage is applied to the base (NPN types).2...The base collector junction should behave as a diode, conducting when a positive voltage is applied to the base. (NPN Types).Note: Many multimeters cannot put out enough voltage to overcome the forward offset voltages, 700mV for silicon devices.Note: Some transistors are too fragile for this kind of testing.Note: Determine the polarity of the multimeter output on ohms ranges.Note: Be very careful when using a multimeter that employs a 9 volt battery for it's ohms ranges...that is enough to blow junctions.
Why do electrons behave like tiny magnets?
a spinning electron produces a magnetic field that makes the electron behave like a tiny magnet
How do electrical charges behave?
Electric charges behave as a matter and it contains three building blocks of matter, they are :electrons, protons and neutrons of which two are electrically charge

How does voltage and resistance behave in a series and a parallel circuit?
The current through each resistor is equal to the voltage across it divided by its resistance for series and parallel circuits.
If Compared to metals and nonmetals how do atoms of semimetals behave when combining with elements of other elements?
They can either lose or share electrons when they combine with other elements. So, depending on the conditions , these elements can behave as either metals or nonmetalss. Durr !
