what is the charge on the subatomic particles represented in figure 4-3? assuming all the particles in the nucleus are visible,
e;ectrons and protons
well you take the number of protons and you subract the number of electrons thus giving you the electric charge of an element
an electron. :) and protons are positively charged and chill out in the Nucleus. The Nucleus also includes Neutrons which are, go figure, Neutral charge. So the negatively charged electrons orbit the Nucleus and inside the nucleus are Protons - positive - and Neutrons - neutral. In fact, what keeps the electrons orbiting is the fact that opposite charges are attracted to one another, so the negatively charged electrons are attracted to the positively charged Nucleus. (the nucleus is positive because it's made up of positive particles - protons - and neutral particles - neutrons - so the overall charge is positive.) :) Hope this helped.
it lines up the magma's magnetic particles.
Leptons are divided into three families with 4 particles (2 particles, plus their two anti-particles) in each family. In the electron family we have the electron, positron, electron neutrino and electron anti-neutrino. Each family has a higher mass than the one before it so the tauon is heavier than the muon which is heavier than the electron. The physical reason for there being three families is completely unknown and will probably win you a Nobel prize if you can figure it out!
You know how many protons and neutrons are present. You can also figure out what element it is if you happen to have a periodic table of elememts.

Number of protons= Atomic number Number of neutrons= Mass number-Atomic number Number of electrons=Number of protons (If there is no charge on the atom)

It is a point.
Are you talking about a sphere?
A nought figure is not represented in Roman numerals because the values of these numerals are self evident.

A closed plane figure which is bounded by straight sides.

The quantity that is represented in this number is 17. To come up with the figure, you multiple the two numbers and then subtract the last number.
