Different metals have different work functions, which determine the amount of energy required to remove an electron from the surface of the metal. Metals with lower work functions typically exhibit higher electron emission because it requires less energy to release an electron. Additionally, the surface properties of the metal can affect electron emission, such as roughness or cleanliness, which can impact the efficiency of the emission process.

Is it possible for two metals to have the same emission spectrum?

No. It is not possible for two metals to have the same emission spectrum. For metals to have the same emission spectrum, they would need for their electrons to have duplicate orbitals. That would be impossible due to the exclusion principle.


What is the emission of electrons from a metals surface when light of a certain frequency shines on it?

How does different medals affect conductivity?

Different metals have varying conductivities due to their atomic structure and the way electrons move within them. Generally, metals with more free electrons, such as copper and silver, have higher conductivities compared to metals with fewer free electrons, such as lead or iron. The presence of impurities or alloys can also impact a metal's conductivity.

How different metels produce differant colour flames when burnt in oxygen?

When different metals are burned in oxygen, the colors arise from the excitation of electrons in the metal atoms. Each metal has a specific electron configuration, leading to unique energy level transitions and emission of light in different colors. The color of the flame is a result of this unique emission spectrum for each metal.


How many valence electrons may metals have?

Different metals have different numbers of valence electrons. The alkali metals have 1. The alkaline-earth, transition, and inner transition metals have 2. Aluminum and those in its column have 3, tin and lead have 4.


Are alkali metals suitable for photo electric emission?

When nonmetals and metals react which atom electrons?

Metals loss electrons and nonmetals gain electrons.


Why do different metals react in different way and with different speed?

Different metals have different atomic structures and electron configurations, which influence their reactivity. Metals with fewer valence electrons tend to be more reactive because they are more likely to lose electrons and form positive ions. Additionally, factors such as the presence of impurities, temperature, and the nature of the reactants can also affect the speed and extent of a metal's reaction.


Do metals take electrons or give electrons to the atoms they bond with?

Metals give up electrons while non-metals gain electrons
