Well... there is a whole group of elements, the noble gases (group 18), that won't usually react/combine with other elements or only with great difficulty. They don't combine well because they all have full outer shells. All atoms lose and gain electrons in order to have 8 outer electrons just like group 18 because they are exceptionally stable. Of the noble gases, helium would be the least reactive with an atomic number of 2.

The atomic number of an atom is equivalent to which of the following?
The atomic number of an atom is equivalent to the number of protons in its nucleus.
If an Atom has an atomic number of 12 What is the atomic number?
Atomic number depends on the number of protons and it doesn't matter how many neutrons there are in that case. Neutrons only contribute to the atomic weight. The atomic number is the same as any other atom of carbon: 6.
What do you get if you subtract the atomic number from the mass number for a particular atom?
mass no - atomic no = number of neutrons in an atom.
The Atomic number of an atom is?
No. Atomic number is the number of protons in the nucleus of an atom. Each element has a unique atomic number that identifies it as that element.
The atomic number is the number of what in the atom?
The atomic number = the number of protons in the nucleus
What is bloods atomic number?
Blood is not a element. Atomic number is about protons. Number of protons in a atom.
Is atomic number the same as mass number?
Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).
What is the atomic number of an atomic indicate?
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
The atomic number is the number of an atom?
The atomic number is the number of _____ an atom
How do you find the atomic number in an atom?
What number of protons there are that's the atomic number. B/c the atomic number is the same as the number of protons. Electrons are usually of the same quantity, however in ions (an atom with a charge) they vary. this is what gives an atom a positive or negative charge.
What is the atomic number of in atom?
atomic number is how much protons(positive atom) and neutrons(neutral atom) are there in an element. therefore an atom does not have an atomic number
What is atomic number of an atom is?
The atomic number of an atom is the number of protons in its nucleus.
What atomic number of an atom is?
The atomic number of an atom is the number of protons in its nucleus.
is a Atomic number the number of an atom's?
Atomic number is the number of protons in a neutral atom
What is the number of neutrons in an atom affects the atomic what?
The number of neutrons in an atom can affect the atomic mass of an atom.
The number of protons in an atom of an element?
It is equal to the no. of electrons in the atom. It is called the atomic number.
How does an atom get its atomic number?
An atom's atomic number is the number of protons within the single atom of an element
