Number of neutrons = Atomic Mass of an isotope - Atomic number of the element; the atomic number of Lr is 103. Lawrencium has many isotopes and each isotope has a different number of neutrons.
In an atom of gold, there are 79 protons and 79 electrons. The number of neutrons for gold may vary by isotope.
All beryllium atoms have 4 protons and 4 electrons. The number of neutrons is characteristic of a particular isotope, not of beryllium as a whole, and may be determined by subtracting 4, the number of protons, from the mass number of the isotope.
Atoms have three subatomic particles; viz., protons, neutrons and electrons. The protons, and neutrons are in the nucleus of the atom and are collectively named as 'nucleons'. Electrons are in energy shells outside and around the nucleus. Atoms with a different number of protns and different elements.
I'm not sure what "ubatomic particles" are. If you may be referring to subatomic particles, these are particles that are smaller than atoms, such as electrons, protons, and neutrons. They are the building blocks of atoms.
6 of each in a neutral (non-ion) atom. The carbon atom contains 6 protons. The number of electrons in any element can vary. These atoms are called ions, where the atoms may lose or gain electrons.

In an atom of gold, there are 79 protons and 79 electrons. The number of neutrons for gold may vary by isotope.
According to Wikipedia neutral nitrogen has 7 protons, 7 neutrons, and 7 electrons. Nitrogen ions may have more or less electrons and other nitrogen isotopes may have more or fewer neutorns.
In normal Helium(He) atom there are 2 electrons, 2protons and 2 neutrons.
protons, neutrons and electrons are the main subatomic particles of the atom. There are the same number of protons as electrons, which is equal to the atomic number. The number of neutrons may vary according to the isotope of the element.
Kinda. There may or may not be smaller things inside the neutrons, protons and electrons, but yes protons neutrons and electrons are the only subatomics that have been proven to exist. There are also the Strong Nuclear Force (which keeps protons from pushing each other away) and the Weak Nuclear Force which has something to do with quarks and W and Z bosons (which are inside protons neutrons and electrons). However these are forces and not particles.
No. Sorry.

Protons/Electrons: 85 Number of Neutrons: 125

30, 30, and 30. Usually.
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
