What kind of basic force pulls electrons close to the atomic nucleus?

The electric force pulls electrons close to the atomic nucleus. The protons in the nucleus have a positive charge, and so attract the negatively charged electrons.

Which has more potential energy an electron close to an atomic nucleus or one far from an atomic nucleus?
In general, electrons farther from the nucleus will have more energy than electrons closer in.
Why does ionization energy decrease down the family?
You question is not very clearly stated but I think I know what you are asking. As you go down the column of any family of elements in the periodic table, you move to increasingly heavier and larger atoms. Their outer electrons are therefore farther from the nucleus, and even though the nucleus is larger and has a larger positive charge, the increased distance is the predominant influence, making the outermost electrons less tightly bound, and therefore more easily ionized, with a lower ionization energy.
Is the valence electron farthest or closest to the nucleus?
No. By definition, valence electrons are the furthest electrons from the nucleus in the atom. They are the electrons most easily removed from (or added to) the atom to create ions. A loophole to this answer might be to say that hydrogen and helium only have 1 and 2 electrons respectively so their valence electrons are close. That's a matter of perspective, as no electrons are really "close" to the nucleus to begin with. A typical comparison is to imagine a grape seed in the middle of a football stadium. The grape seed represents the nucleus, and an electron would be a speck of dust on the outside of the stadium.

Why do you suppose that an energy level close to the nucleus can hold fewer electrons than one farther away from the nucleus?
it has to do with quantum numbers N,L, and M
Why nonmetals do not have free electrons which conduct electrical energy?
Because the outer shells are very close to the nucleus and the number of electrons in the outer shells are between 4-8. Therefore, they are not freed from the nucleus easily rather they look for some more electrons to fill its outer shell which is technically called as covalent bond.

Is this statement correct atoms are made up of nucleus and electrons composed of protons whose number is called the atomic number and neutrons whose numbers added together make the mass number?
It's close, but an atom is made of a nucleus and electrons. The nucleus is made of protons and neutrons. The number of protons equals the atomic number of the element, and the atomic mass is the number of protons plus neutrons.
How do you know protons are found in the nucleus?
The atomic number tells you how many protons are in the atomic nucleus. The atomic mass is the amount of protons plus the amount of neutrons in the atomic nucleus. So if you take the atomic number and subtract it from the atomic mass, it will give you the number of neutrons in the atomic nucleus.
What holds electrons in their shells?
The electrons "orbit" the nucleus of an atom. They do so because they are attracted to the positive charge of the protons inside the nucleus. They do not usually leave the atom because of this attraction, and do not usually fall into the nucleus because they are moving.
What do you get if you add one neutron to a hydrogen nucleus?
If you add the number of protons and neutrons in an atomic nucleus, you get the number of nucleons. This is usually a good approximation to the atomic mass in amu, since both protons and neutrons have a mass that's pretty close to one amu. The number will be slightly off, because electrons contribute as well, protons and neutrons don't have exactly the same mass, and there's something called the atomic mass defect that has to do with the binding energy of the nucleus, but it should be fairly close.
Do electron like to be close to each other?
As per modern atomic model, the neutrons would be packed along with protons in the nucleus because of nuclear force. The electrons are considered to be revolving around the nucleus. So electrons are not packed close to the neutrons.
What is closer to nucleus the stronger the attractive force?
When it is close to the nucleus because the postively charged protons attract the negatively charged electrons

How do electrons act in covalent bond?
Given that electrons repell other electrons while attracting protons in atomic nucleii, electrons interact in covalent bonds by finding an arrangement which brings them as close as possible to as many protons as possible while remaining as far as possible from other electrons. The particular feature of a covalent bond which differentiates it from other types of bonds is that a given electron does not limit itself to a single atomic nucleus, but orbits multiple nuclei.
Subatomic particles are closest in mass?
Proton and neutron (components of the atomic nucleus) have masses very close.
Is the valence electron farthest or closest to the nucleus?
