Why are solid metals really good conductors?
Metals are made up of atoms which are joined together tightly in a the solid state. Metals are having free electrons around atoms which are the ones that carry the heat energy or electrical energy for one end to the other.
In which energy level are the electrons with the least energy located?
The maximum number of electrons that can occupy a specific energy level can be found using the following formula:Electron Capacity = 2n2The variable n represents the Principal Quantum Number, the number of the energy level in question.
Why metals are good conductors of electricity give at least 4 reasons?
Metals are good conductors of electricity because :- 1.Metals they have free electrons which contribute in conduction of electricity. 2.Interms of energy bands metals they have no forbidden gape between conduction band and valence band, hence create easy overlapping of electrons from the valence band to conduction band. 3.Metals are ionizing by loosing electrons in their outermost shell so they can give out electrons, as a result of having the habit of conducting electricity because of these free electrons. 4.All metals are solid with great thermal capacity and low impurities, this feature gives all metals to be used as utensils as well as electric wires, since all metals are good conductors of heat and electricity.
Why alkali metals give deep blue colour when react with ammonia liquid?
alkali metals give out electrons which is surrounded by ammonia. this is having blue colour
What is actual 3 dimensional region in space having the highest probability of containing the electrons is known as?
This is the electron cloud.
Do metals and non metals become more chemically stable when they fill or empty their outermost energy levels?
When they fill their outermost energy levels. Metals will WANT more electrons and Non-Metals will have EXTRA electrons to give. So in a way, Metals will actually fill their outermost energy levels while Non-Metals will empty them; all with the goal of having a FULL valency shell which is stable. This is the basis for ionic bonding.
What kind of elements has less than 4 valence electrons?
Boron group, transition metals, alkaline earth metals and alkali metals are listed in the Periodic Table are having less than four valence electrons

When metals form ions they tend to do so by?
When metals form ions, they tend to do so by losing their electrons to gain a positive charge. Losing negatively charged electrons causes the metals to become more positive due to having more protons.
What waves have the highest amount of energy?
The waves having the hightest amplitude, then it has the hightest Energy.
Why alkali metals give deep blue colour when react with ammonia liquid?
alkali metals give out electrons which is surrounded by ammonia. this is having blue colour
What is aufba rule?
Electrons will occupy orbitals having the lowest energy first, and then in order of increasing energy.
What happens when the electrons relax?
As excited electrons drop back to lower energy levels in the atom, photons having the energy of the difference between the two electron energy levels are emitted from the atom.
Positive ions usually form from?
Usually, negative ions are formed by losing of electrons from the atom. Due to which, that atom get positively charged( due to having more number of protons than electrons).
Why are Metals are often referred to as electropositive?
Why metals are electron positive in nature?Because by having an octet as their outer electron shell they will become more stable. For metals it's easier to shed electrons to achieve an octet than it is to achieve it by gaining them.
