a larger nuclear charge
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
The period 4 element with the smallest atomic radius is chlorine, which has a greater number of protons in the nucleus pulling the electrons closer, making it smaller compared to other elements in the same period.
Type your answer here... Potassium (K)
Magnesium, an element with 12 protons, does not have a fixed number of neutrons. It exists as many isotopes (differing versions of the same element with the same number of protons, but a different number of neutrons), three of which are Mg-24, Mg-25, and Mg-26. [Atomic symbol-Atomic mass] To find the number of neutrons, take the atomic number from the atomic mass: for example, 26 - 12 = 14. This means Mg-26 has 14 neutrons. However, to answer your question, the most common isotope of Magnesium is Mg-24. This is the case for most elements up to and including atomic number 20; the number of neutrons equals the number of protons. So; the most common isotope of Magnesium, Mg-24, with a relative abundance of about 79%, has 24 - 12 = 12 neutrons.
Scandium is slightly larger than Titanium due to one unit less nuclear charge.
Barium is smaller than caesium. Different elements have different atomic radii, with caesium having a larger atomic radius compared to barium.
Magnesium's atomic number is 12. Thus, to be electrically neutral, it must have 12 protons and 12 electrons. 24Mg is magnesium's most common isotope having 24 - 12 = 12 neutrons.
smaller
The neutral atom is bigger. The ion would be smaller because in order for magnesium to become a positively charged ion, it has to give up its valence electrons, which results in the removal of the outermost energy level. So instead of having three energy levels, the ion now has only two.
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Magnisium has a different atomic mass to sodium plus they are in 2 separate periods, but im not sure about having more protons :)
The period 4 element with the smallest atomic radius is chlorine, which has a greater number of protons in the nucleus pulling the electrons closer, making it smaller compared to other elements in the same period.
Fluorine is larger than hydrogen because it has more protons, neutrons, and electrons in its atomic structure. This results in fluorine having a higher atomic mass and a larger atomic radius compared to hydrogen.
Type your answer here... Potassium (K)
The atomic size of potassium is approximately 231 picometers (pm). It is a relatively large atom due to having 19 protons and electrons, which results in a larger atomic radius compared to many other elements.

"Atomic" is an adjective meaning "having to do with an atom."
