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.
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.
Atomic emission spectrometry is limited to alkali metals.
Metals loss electrons and nonmetals gain electrons.
Electrons in a metallic bond are delocalized, meaning they can move freely throughout the metal lattice. This gives metals their unique properties such as high electrical and thermal conductivity. The mobility of electrons also allows metals to be malleable and ductile.
Atomic emission spectrometry is a selective method for quantifying some types of metals. It is also cheap and robust. However, atomic emission spectrometry is only applicable to the determination of alkali metals and some alkaline earth metals.
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.
photoelectric effect
the external energy given to electrons,thier kinetic energy increases.thus electrons move from metal surface

Thrse electrons are involved in chemical reactions.

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.
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.
yes alkali metals are suitable for photo electric emission
Metals loss electrons and nonmetals gain electrons.
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.
Metals give up electrons while non-metals gain electrons
