How many number of protons and electrons for this atom or ion?
The atomic number tells you the number of protons. For instance oxygen has an atomic number of 8, and hence it has 8 protons. Electrons are slightly more complicated. In a neutral atom, the number of electrons is always the same as the number of protons. However, if the atom is charged (i.e. it is an ion), it may have more electrons than protons (negatively charged) or less electrons than protons (positively charged).
How scientists can tell the difference between elements if they cant do it by neutron number or electric charge?
The important thing is the number of positrons in the nucleus - this is the atomic number.
The closer a is to the nucleus the stronger the attractive force?
Yes, that's correct. The closer an electron is to the nucleus of an atom, the stronger the attractive force between the nucleus and the electron. This attraction is due to the electrostatic force between the positively charged nucleus and the negatively charged electron.
Why are atomic numbers listed as whole numbers?
The atomic number is derived from how many protons are present in the nucleus of an atom. Becaue you cannot have a fraction of a proton present in an atom, atomic numbers must be non negative integers.
Elements cant be split up into anything simpler by?
Elements are made up of atoms, which cannot be further divided without losing their chemical properties. Each element is composed of a unique type of atom distinguished by the number of protons in its nucleus.
The diameter of an atom is?
in the bottom Atomic nucleus is at the center of the atom.
What are 3 subatomic particles that make up an atom and their location?
- Electron - surrounding the nucleus in orbitals/shells with a negative charge and are in a electron cloud - Proton - make up the nucleus with the positive charge - Neutron - make up the nucleus with no charge what so ever
How can you find the nucleus with no mass number?
you cant get the # of neutrons if there is no atomic mass because you have to subtract the atomic # from the atomic mass #. so there is no way that u can find the # of neutrons without the atomic mass it is needed!
Does an atoms nucleus have a positive or negative charge?
it cant have any charge at all. atoms have an equal amount of protons and neutron therefore the give off no charge. if they did give off a charge they would no longer be atoms they would be ions
Electrons spin in shells around the nucleus The closest shell n equals 1 can contain a maximum of?
i cant answer that sorry

What would happen if an atom had a negatively charged nucleus?
It would be a positively charged ion, and would react with negatively charged ions having more electrons than protons. A simple example: table salt: sodium chloride. The positive sodium ion is attracted to the negative chloride ion. This is a common occurrence between atoms that easily donate or receive electrons, and form what are called ionic bonds.

Why cant electron exist in the nucleus?
When a nucleus is formed, the nucleons involved, that is, the protons and neutrons that are going to be forming the nucleus, are "squeezed" together in the fusion reaction. During this reaction, the stong interaction or strong nuclear force mediates the conversion of some of the mass of each proton and neutron that is going to make up the new nucleus into nuclear binding energy. The binding energy, or nuclear glue, is created from a bit of the mass of each nucleon involved through what is called mass deficit. If any electrons are present in the vicinity of the fusion reaction, they are "locked out" of the reaction by the strong interaction. The electron will not be permitted to become involved in the fusion reaction because it does not have the "right stuff" to participate. That is why no electrons can be in a nucleus. Note that in some kinds of nuclear decay called beta minus decay, an electron is created within the nuclues, and it is quickly ejected. The electron did not exist in that nucleus, but was created through the mediation of the weak interaction or weak nuclear force. A neutron was converted into a proton and an electron and an antineutrino, and then the electron was kicked out of the nucleus.
How do you determine the number of protons in the nucleus?
The number of protons in an atom determines the chemical identity of that atom. (And only that, by the way.) We use the atomic number to state the exact number of protons in all atoms of a given element. Hydrogen has the atomic number 1 because every atom of hydrogen has exactly one proton. Also, every atom with exactly one proton is hydrogen. Helium is atomic number 2, and the same thing applies. All helium atoms have exactly 2 protons, and all atoms with exactly 2 protons are helium atoms. To determine the number of protons in a given atom, look at which element it is and find it on the periodic table or on a list of the elements. Then find its atomic number, which will be the exact number of protons in every atom of that element.
Why cant a 3 ion of aluminum be made by adding 3 protons to an aluminum atom?
Adding protons changes the element, creating a new element with a different atomic number. The element with 3 protons is not aluminum, so adding 3 protons would create a different element rather than a 3+ ion of aluminum.
