Most of an atom is empty space. If an atom were about as big as a baseball stadium, the nucleus would be the size of a pea in the very center and the electrons would be somewhere on the outside edge.What makes an atom of gold different from an atom of iron is the number of ...
If the number of (b) ___ changes, the atom is of a different element. Atomic Structure: Atoms, the tiny particles that make up elements and combine to form functional molecules, are composed of three particles. Protons have a po...
Here’s why that’s important. Whenever you emit a single photon, it almost always collides with another hydrogen atom, exciting it and putting it in an energized state: precariously close to its reionization energy. 99.999999% of the time, reionization of a new atom is going to occur beca...
The majority of an atoms’ mass comes from the protons and neutrons that make up its nucleus. Electrons are the least massive of an atom’s constituent particles, with a mass of 9.11 x 10-31kg and a size too small to be measured by current techniques. Protons have a mass that is 1,...
Protons are positively charged particles in an atom's nucleus, while electrons are negatively charged particles orbiting the nucleus.

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. What does the nucleus do? The ...
What is the daughter nucleus when an atom undergoes electron capture? Daughter Nucleus: The daughter nucleus refers to the nucleus of the atom after it undergoes nuclear decay. Before nuclear decay, the nucleus is called the parent nucleus. This helps to identify the direction of change...
