For an average atom, the radius lies around 10 nm and the nucleus around 1 pm.
From the given elements, Mg has the largest atomic radius, hence the size.
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
all atoms are generally the same size, so "large atoms" would mean molecules.
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.

No, Dalton's atomic theory did not include the idea that all atoms of all elements are the same size. Instead, he proposed that atoms of different elements have different sizes and weights.
Not necessarily. The atomic radius of an element is determined by the size of the atom's electron cloud. While atoms of the same element would typically have the same atomic radius, atoms of different elements can vary in size due to differences in their electron configurations and the number of protons in their nuclei.
The atomic size of hydrogen peroxide (H2O2) can be determined by measuring the distance between the nuclei of the hydrogen and oxygen atoms in the molecule. The size is influenced by the arrangement of the atoms in the molecule and the bond lengths between them. The atomic size of hydrogen peroxide is relatively small compared to larger molecules, such as proteins or DNA.

Atomic Radius means the size of the atoms, the distance from the atomic nucleus to the outermost electron orbital.
The atomic radii is the measure of the size of the atoms in a chemical element. This is the distance from the nucleus to the boundary of the electrons' cloud.
From the given elements, potassium has the largest atomic radius.
The Smaller Atoms [H to Ca] are in the [single] Angstrom range.
The half distance from center to center of two atoms bonded together is known as the covalent radius, which represents half the distance between the nuclei of two bonded atoms. It is a measure of the size of an atom when it forms a covalent bond with another atom.
