An electron and a neutron have the same de broglie wavelength. which is true? (a) the electron has more kinetic energy and a higher speed. (b) the electron has less kinetic energy but a higher speed (c) the electron has less kinetic energy and a lower speed (d) the electron and neutron have the same kinetic energy but the electron has the higher speed (e) the neutron has more kinetic energy but the two have the same speed

Explanation:

The mass of electron,

The mass of neutron,

The De-Broglie wavelength is given by :

p is the momentum, p = m v

For electron,

For neutron,

Since, an electron and a neutron have the same de Broglie wavelength. So,

The mass of electron is less than the mass of neutron. So, the speed of electron is more than than the speed of neutron. As the kinetic energy is directly proportional to the mass. So, the correct option is (a) The electron has more kinetic energy and a higher speed.

answer; ///(c); ///bronchi i do believe this is the correct answer,; plz check first..good luck

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
