The nuclear charge in the 4th shell of an argon atom is +18, as argon has 18 protons in its nucleus. The nuclear charge is equal to the number of protons in the nucleus of an atom.
Atomic radius is the measure from the middle of an atom to the outter edge. Usually mesured between two atom. Measure from the middle of one atom to the middle of another and then divide by two.
The radius of an atom typically decreases when moving from left to right across a period in the periodic table due to increasing nuclear charge. It increases when moving down a group in the periodic table due to the addition of energy levels.
Scandium empirical atom radius: 160 pm Scandium calculated atom radius: 184 pm
The atomic radius is the distance from the nucleus to the outermost electron shell of an atom. Atoms consist of a dense, positively charged nucleus surrounded by a cloud of electrons in specific energy levels or shells. The size of the atomic radius increases as you move down a group in the periodic table due to the addition of electron shells, and decreases as you move across a period due to increasing nuclear charge.
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.

the further right you go on the periodic table, the atomic radius decreases. the further down you go on the periodic table, the atomic radius increases. you can determine where an atom is generally placed on the periodic table based on its atomic radius.
The atomic number of 11 means there are 11 protons in the nucleus, giving the atom a nuclear charge of +11. The atom in question is a Sodium atom.
The only way to change the number of protons in an atom is with a nuclear reaction.
The number of neutrons and protons in the nucleus of the atom.
As we move across the period, there is an increase in the atomic number i.e., there is an increase in the number of protons inside the nucleus. This means, there is more nuclear force. This nuclear force pulls the electron orbits as close as it can. thus, the radius of the atom decreases. Hence the atomic size decreases.
the mass number is number of protons in an atom, plus the number of neutrons.
Protons determine the nuclear charge of an atom. Each proton carries a positive charge and is located in the nucleus of an atom. The number of protons in an atom determines its atomic number and therefore its nuclear charge.
Energy gap depends on the energy of a particular energy level at a given radius in analogy with the energy of a hydrogen atom neing directly proportional to atomic number and inversely proportional to the square of nth energy level. It does not depend on the smallness of an atom.
The nuclear charge in the 4th shell of an argon atom is +18, as argon has 18 protons in its nucleus. The nuclear charge is equal to the number of protons in the nucleus of an atom.
