What happens when an atom has an extra neutron?
Adding or removing neutrons from the nucleus are how isotopes are created. … Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom’s atomic number. So, adding or removing protons from the nucleus changes what element that atom is!
Is Helium a metal?
Helium is a nonmetal element. It is the second element on the periodic table, following hydrogen, and is part of the highly stable noble gas group. Notably, it has the lowest boiling and melting points of all elements, which is why it is almost always found as a gas. …
What is it called when an atom has more neutrons?
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
What does adding neutrons to atoms make?
Atoms always have an equal number of protons and electrons, and the number of protons and neutrons is usually the same as well. Adding a proton to an atom makes a new element, while adding a neutron makes an isotope, or heavier version, of that atom.
