Electron Deceleration

My textbook states the following: When an electron strikes the metal, it will be attracted towards the nucleus of an atom in the metal. This will cause it to change both its speed and direction - in other words, it decelerates.

But I fail to see why the electron decelerates. They electron is attracted to the nucleus. So it must accelerate towards the nucleus right? And once it collides with the nucleus, it must lose its energy and stick to the nucleus. What am I missing?

its an inelastic collision?

What is the context?

See here for a maybe relevant extract: http://www.columbia.edu/itc/hs/dental/sophs/material/production_xrays.pdf

I am not sure about that

kinetic energy is not comserved and the particle slows down aka decelrates? I dont know. Where do you find these questions. I am doing edexcel.

I am doing CIE. I have a chapter on medical imaging.
