What determines the atomic number and the mass number? How do you determine the number of neutrons in an atom? The number of protons in the nucleus of an atom of an element determine _____. The number of protons
If an atom with a mass number of 202 has 122 neutrons, it is an atom of which element? What determines the atomic number of an atom? What element has 6 protons, 8 neutrons, and six electrons? What element has 4 protons 5 neutrons and 2 electrons?
The main reason the atomic number is important is because it's how you identify the element of an atom. Another big reason it matters is because the modern periodic table is organized according to increasing atomic number. Finally, the atomic number is a key factor in determining the propertie...
It is the number of protons that determines the atomic number, e.g., H = 1. The number of protons in an element is constant (e.g., H=1, Ur=92) but neutron number may vary, so mass number (protons + neutrons) may vary. The same element may contain varying numbers of neutrons; ...
than electrons and slightly bigger than protons, the number of neutrons within the nucleus of an atom determines the number of isotopes that a particular atom can form. Neutrons are very stable in their bound form within the atom; however, free neutrons are extremely unstable and undergo decay....

The number of protons in an atom is unique to each element. For example,carbonatoms have six protons,hydrogenatoms have one andoxygenatoms have eight. The number of protons in an atom is referred to as the atomic number of that element. The number of protons also determines the chemical be...
... The number of protons determines the identity of the atom. So, hydrogen has 1 proton, oxygen has 8 protons, iron has 26 protons, and so on. The number of neutrons is usually fixed for a particular atom (for example, the most common form of carbon has 6 neutrons), but this does...
Atomic Structure: The nucleus is the dense core of the atom, containing protons and neutrons. Electron shells are energy levels where electrons reside. The arrangement of electrons determines an atom’s chemical properties and its ability to form bonds. Quantum Mechanics: Electrons do not orbit the...
Centripetal and centrifugal forces are two terms used to describe the physics of circular motion — but only one of them is real. The centripetal force keeps an object moving in a circle and is always pointed toward the center of that circle. For instance, the gravitational force of the sun...
