Does a metal gain or lose an electron when it reacts with a nonmetal?
The metal tends to lose the electron because it has a higher electron affinity, and the nonmetal tends to gain the electron because it has a higher electronegativity. This has to do with the placement of the element on the periodic table. The further to the right you go, the more the element wants to gain electrons in an ionic compound.
How can one calculate the work function of a metal?
The work function of a metal can be calculated by measuring the minimum amount of energy needed to remove an electron from the metal's surface. This can be done using the photoelectric effect, where light of varying frequencies is shone on the metal surface and the energy required to eject an electron is measured. The work function is then equal to the energy of the incident light that causes electron emission.
In what kind of microscope the specimen is coated with a thin film of a heavy metal usually gold then observed by using an electron beam that is directed down on the?
Scanning electron microscope (SEM) is the kind of microscope where the specimen is coated with a thin film of a heavy metal like gold and then observed using an electron beam that is directed down on it.
What is the work function of the unknown metal?
The work function of an unknown metal is the minimum amount of energy needed to remove an electron from its surface.
Which element is the most reactive non metal?
Fluorine is the most reactive non-metal element. It readily gains an electron to achieve a stable electron configuration, making it highly reactive.
Is potassium the electron lender or borrower?
Potassium is an electron donor. It donates one electron to achieve a more stable electron configuration.
How can hydrogen act ad a metal and a nonmetal?
Hydrogen has 1 electron. It can easily gain or lose electron to form metal or non metal
When an alkali metal reacted with a non metal what happens to the loan outer shell electron?
The electron outside the shell donate its electron to the one inside the shell
What alkali metal requires 4 electron shells?
Cesium (Cs) is the alkali metal that requires 4 electron shells as it has the electron configuration [Xe] 6s1.
What alkali metal has two energy levels?
Lithium is the alkali metal that has two energy levels in its electron configuration. Its electron configuration is [He] 2s¹.
Is flouride a metal or non metal?
Fluoride is an ion formed by the nonmetal fluorine.
Why does the metal's radius get smaller and the nonmetal's radius get larger during an ionic bond?
Because the metal loses an electron (making it smaller) and the non metal gains that electron, making it larger.
Is protactinium a lender sharer or giver of electrons?
As a metal protactinium is a giver of electrons.
What happens to the valence electron in an alkali metal when it combines with a halogen gas?
This electron is lost.
What particle floats freely in metal?
an electron.
Is gold a electron donor or acceptor?
Gold is a relatively inert metal and does not typically act as an electron donor or acceptor in chemical reactions. Its electron configuration makes it stable and less likely to participate in redox reactions.
The outer electron configuration of an alkali metal has?
The outer electron configuration of an alkali metal is one electron in the s subshell. This electron is easily lost to form a cation with a full valence shell, resulting in the high reactivity of alkali metals.
