What force of attraction is keeping the soccer ball at the bottom of the ditch?

The force of gravity is keeping the football in the ditch. player is trying to kick a ball out of a ditch.


Subsequently, question is, what determines the position and height of each peak in a photoelectron spectrum? 2. What determines the position and the height (intensity) of each peak in a photoelectron spectrum? The position of each peak is identified by the ionization energy, the height of each peak identifies the ratio of electrons in each level or orbital.

Simply so, which type of energy needs to be overcome to remove an electron from the atom?

By definition, the first ionization energy of an element is the energy needed to remove the outermost, or highest energy, electron from a neutral atom in the gas phase.

What force of attraction holds the electron in the hydrogen atom?

the electromagnetic force

What is interesting about the photoelectron spectrum for hydrogen?

What is interesting about the photoelectron spectrum for hydrogen atom and the first ionization energy for hydrogen? Since hydrogen has only one electron we would expect its photoelectron spectrum to consist of a single peak. The energy (y-axis) is 1.312 MJ mol-1.

How do you find the ionization energy of a photoelectron?

By using photoelectron spectroscopy, the ionization energy is determined by subtracting the energy of the incoming photon from the measured kinetic energy of the ejected electron.

How much energy is required to remove an electron?

Re: Calculate energy required to remove an electron All you would have to do is use 150.6kJ/mol and divide by 100 and get 1.506 and raise to 10^5.

Why is energy required to remove an electron?

Electrons in an atom are held there by the force of attraction exerted by the positive charge of the nucleus on the negative charge of the electron. Energy is required to remove an electron from atom to overcome this attractive force.

What is a charged atom called?

An ion is a charged atom or molecule. When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION.

How do you calculate binding energy?

The binding energy (BE) of a nucleus is the energy needed to separate it into individual protons and neutrons. In terms of atomic masses, BE = {[Zm(1H) + Nmn] − m(AX)}c2, where m(1H) is the mass of a hydrogen atom, m(AX) is the atomic mass of the nuclide, and mn is the mass of a neutron.

What is the relationship between the ionization energy of an electron and the net attractive force?

Therefore the closer the electron to the nuclear the higher the attraction force, and thus the higher the energy required to overcome this attraction and remove the electron. Therefore the smaller the radius the higher the ionization energy, and the bigger the radius the lower the energy need.

What is meant by first ionization energy?

Definition. The first ionisation energy is the energy required to remove one mole of the most loosely held electrons from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+.

What does the number of peaks in a PES spectrum reveal?

The PES spectrum shows two peaks, which represent electrons in the 2 different subshells of lithium ( 1 s 1s 1s and 2 s 2s 2s ). The 1 s 1s 1s subshell of lithium contains twice as many electrons as the 2 s 2s 2s subshell ( 2 vs. 1 1. 1), so the peak closer to the origin must correspond to lithium’s 1 s 1s 1s subshell.
