What types of atoms have the same number of electrons and protons?
A) all atoms
B) stable atoms
C) ions
D) metalloids
No, all atoms that are NOT ions. For example Li + ion has one more protons than electrons so has a charge of +1. Cl- has one more electrons than protons.
so answers?
Its Stable Atoms
The correct answer is A) all atoms.
To understand why all atoms have the same number of electrons and protons, we need to revisit the basic structure of an atom. Atoms consist of three main subatomic particles: protons, neutrons, and electrons. The protons have a positive charge, neutrons have no charge, and electrons have a negative charge.
Protons are found in the nucleus, which is located at the center of the atom. Neutrons are also found in the nucleus alongside the protons. Electrons, on the other hand, are found in orbitals or energy levels surrounding the nucleus.
The number of protons determines the atomic number of an element, which is unique to each element. For example, the element hydrogen has 1 proton, while the element carbon has 6 protons. Electrons are negatively charged particles that balance out the positive charge of the protons in the atomic nucleus. Therefore, the number of electrons in a neutral atom is always equal to the number of protons.
To find the number of protons and electrons for a specific atom, you can look up the atomic number of the element on the periodic table. The atomic number is usually located above the symbol of the element. For example, carbon has an atomic number of 6, which means it has 6 protons and 6 electrons.
In summary, all atoms have the same number of electrons and protons, making option A) the correct choice.
C) ions
Well, here I go again. I don't like any of the answers although a comes close as does b.
I don't like a because it says ALL atoms. I would prefer that it say all atoms OF THE SAME ELEMENT. I don't like b because it has the word "stable" in there. Even unstable radioactive element have equal number of electrons and protons so I don't know what stable as to do with it. Of course c and d are wrong.
