the mass of protons + the mass of neutrons = mass of the element
atomic mass
The Atomic Mass number tells the atomic mass of an element. The mass is calculated as the mass of all the protons and neutrons in the center of an atom.
It determines which element, which all have their own properties so yes. The mass number just determines the isotope which only affects their stability
Usually, its mass determines its weight.
mass= density times volume
Yes, an element has mass. The smallest unit of an element is the atom, and the atom's mass is the amount of matter in it: the neutron(s), proton(s), and electron(s). Because the number of protons determines an element's identity, and protons have mass, elements always have mass (though this can be a tiny, almost immeasurable mass).
No, the mass number of an element does not determine how a compound will form. The properties of compounds are determined by how the atoms of different elements are bonded together, which involves their electron configurations and interactions. The mass number only reflects the total number of protons and neutrons in the nucleus of an atom.
The valence electrons
The mass and acceleration of an object determines its momentum, which is the product of mass and velocity. Momentum is a vector quantity that describes the motion of an object.
The mass of an object determines its inertia. Inertia is the resistance of an object to changes in its state of motion, and the greater the mass of an object, the greater its inertia.
