The bigger number (Atomic Mass) is the amount of protons (=same amount of electrons unless specified) and nutrons in an atom. The smaller number (atomic number) is the amount of protons only
atomic number
The nucleus of an atom contains protons and neutrons, which are collectively referred to as nucleons. The number of particles inside the nucleus varies depending on the element, as it is determined by the number of protons and neutrons present.

The period tells you how many energy levels an atom has.
The atomic number of an atom tells you the number of protons in the nucleus of that atom. It determines the element to which the atom belongs on the periodic table. Each element has a unique atomic number.
The atomic number tells you how many protons and electrons are in a specific element.Atomic number tells us about protons. Number of protons that atom contains.
yes they do
atomic number
Atomic number tells how many protons are inside an atom's nucleus and therefore also how many electrons the atom has. An atom's mass number is the number of protons AND neutrons in the atom's nucleus and this will vary for each isotope of an element.
The Periodic Table tells you how many protons are in an atom by their Elemental Number. In other words, yes, the Periodic Table tells you how many protons are in an atom.
The answer depends on the atom! The total number of subatomic particles in an atom of an isotope is the sum of the mass number and the atomic number of the isotope; the mass number counts the protons and neutrons together, and the atomic number recounts the number of protons, which in a neutral atom must be the same as the number of protons.
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
The nucleus of an atom contains protons and neutrons, which are collectively referred to as nucleons. The number of particles inside the nucleus varies depending on the element, as it is determined by the number of protons and neutrons present.
An atom's atomic number tells us its number of protons. Lithium's atomic number is 3. Thus lithium has 3 protons per atom.

The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
For an atom of xenon, the number of particles in the nucleus would be the sum of the protons and neutrons. Xenon has 54 protons and usually around 78 neutrons, so the total number of particles in the nucleus would be around 132.
