A radio pulsar or a rotation-powered pulsar. A link is provided for more information.
neutron star
It is extremely unlikely that a neutron star (or any star or planet) will collide with the Earth, so this is not something that you need to worry about, however, if a neutron star were to collide with the Earth, the Earth would be captured by the intense gravitational field of the neutron star, and would be absorbed by the star. Under sufficient pressure, electrons and protons will merge to form neutrons, and so the atomic matter of which the Earth is composed can be converted into pure neutrons.
Neutron stars are made almost entirely of neutrons. These neutrons are formed when the star implodes, causing the orbiting electrons of the atoms to interact with the protons in the nucleus. So, it is safe to say that neutron stars contain no electron.
Neutron stars are created when a massive star runs out of hydrogen to burn and become a supergiant. The supergiant will then explode and only leaves a core and a nebula. The dense core will then become a neutron star or a black hole.
First off, the Sun is not a big star. It is a Main Sequence star, which means it's an average size star. Second, at the formation of your Solar System, gravity caused rocks to start getting closer together and spinning. Eventually, the friciton and gravity was so great, and became so hot, the spinning rocks became a star, known as the Sun.
It is still called a neutron star. Depending on how we observe it, it may also be called a pulsar.
Yes. A pulsar is a rapidly spinning neutron star.
A young neutron star. Really - that is what a neutron star is. If the neutron star's magnetic field is pointed towards Earth, then it is referred to as a pulsar - because of it's rapid pulsations [See related question] but it is still a neutron star.

"Small but very dense" sounds like the description of a neutron star or "collapsed matter star". Theoretically, a black hole (the only thing more dense) has no physical size at all. So, "neutron star". If the neutron star is spinning rapidly, they are called "pulsars" for the radio-wave pulses that they generate.
A pulsar is a rapidly spinning neutron star that releases regular pulses of electromagnetic radiation from its magnetic field
If the beam is directed towards Earth, it's called a Pulsar.
ANY star will spin; you can't avoid it from having SOME spin.A "degenerate star" would probably refer to one that is made up of degenerate matter. That can either be a white dwarf, or a neutron star.
A pulsar is a rapidly-spinning neutron star, the remains of a supernova explosion.
Not exactly, while a pulsar is a specific type of neutron star (that being a "spinning neutron star") and a binary system is a pair of stars orbiting each other, a pulsar does not need to be part of a binary system. It would be possible, however to have a binary system with one of the pair being a pulsar and the other a neutron star (assumed to be the non-spinning or "normal neutron star" variety).
