What describes the size of an atom?
The size of an isolated atom cannot be determined simply because scientists can't locate electrons outside of the nucleus. In addition to this, the size can be estimated by taking half the distance of adjacent atoms (in a solid)
What is the effect of an additional electron have on atomic size?
According to me the atomic size of an atom increases or decreses with the change in the number of shells. As atomic size is defined as the distance between the nucleus and valence shell of an atom. So, the addition of an electron does not effect the atomic size. As we can see in the periodic table that while moving along a group the number of electrons increases along with increase in no. of shells, while the atomic size tends to be increase with addition of shells and neglecting the addition of electrons. Same is the case while moving along a period. Atomic size decreases while the attraction between increased nuleus charge increases . Thus the size of the atom decreases.
Is atomic mass and atomic diameter the same thing?
No, atomic mass and atomic diameter are not the same thing. Atomic mass refers to the mass of an atom, which is the sum of the protons and neutrons in the nucleus, while atomic diameter refers to the size of the atom, often measured as the distance between the nuclei of two bonded atoms.
What is the average size of atom?
The average size of an atom is around 100 picometers (10^-12 meters). This size can vary depending on the specific element and its atomic number.
Is a gold atom or a hydrogen atom larger?
Atomic (covalent) radius of hydrogen is 31 pm. Atomic (covalent) radius of gold is 136 pm.
What is the size of sodium's atom?
Atomic size of sodium is 186
What do you mean by the atomic radius?
Size of a nutral atom
What is the Atomic size of oxygen?
The atomic size of oxygen is approximately 60 picometers (pm). The atomic size refers to the distance from the nucleus to the outermost electron shell in an atom.
What is the size of sodium atom?
The approximate size of a sodium atom is about 0.186 nanometers (nm) in radius. Sodium is a relatively large atom compared to hydrogen or helium because it has more electrons and protons, leading to a larger atomic radius.

Is smaller than the atomic radius of oxygen?
Yes, the atomic radius of oxygen is larger than the size of an atom. The atomic radius represents the distance from the nucleus to the outermost electron shell of an atom.
Definition Of Atomic Size?
Atomic Size is the going across any period, atomic radius is decreasing in size due to the increase in the number of electrons is attracted toward the nucleus. Going down any group, there are a large increase in atomic size. The size of an atom depends on where the electrons are distributed outside the nucleus.
What is the average size of atom?
The average size of an atom is around 100 picometers (10^-12 meters). This size can vary depending on the specific element and its atomic number.
Is the atomic size of magnesium atom greater than that of be?
If by Be you mean beryllium then yes.
What trend do you note for the atomic radii of period 3?
The size of atom decreasing.
