Does O or F have a smaller atomic radius?
Both F and O are in period 2 meaning they both have 2 shells of electrons. But, F has 9 protons attracting those other electrons wheres O has only 8 protons attracting those outer electrons, This will tend to make F a little smaller in radius than O.
Which element has smaller size O or F?
Fluorine is smaller than oxygen because as we move across a period the size of the elements decreases.
Is O or NE smaller?
The answer is Ne. These 3 elements belong to the same period (row) with Ne having 1 more proton ( and electron) than F, which itself has one more proton ( and electron) than O.
Which element has the largest atomic radius O or F?
Francium
Explanation: Francium has the largest, Helium has the lowest. Atomic radius increases as you go to the left and downward due to the attraction of electrons and the nucleus in an atom.
Why is F smaller than ne?
Ne has its valence electrons in a higher energy level than F. The valence electrons in Ne feel a greater Zeff than those in F. Fhas more protons in its nucleus than Ne. Ne has more mass than F making it larger.
Which of the following elements has the smallest atomic radii?
Helium has the smallest atomic radius. This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus.
Is O larger than ne?
Thus, helium has the largest first ionization energy, while francium has one of the lowest. From top to bottom in a group, orbitals corresponding to higher values of the principal quantum number (n) are being added, which are on average further away from the nucleus….Periodic Trends — Ionization Energy.

What has the smallest atomic radius?
Helium
Helium has the smallest atomic radius. This is due to trends in the periodic table, and the effective nuclear charge that holds the valence electrons close to the nucleus. Atomic radius decreases as you move across a period from left to right and decreases as you move up a group from bottom to top.
Which of the following elements has the smallest atomic radius quizlet?
all of them are in period 3. Silicon has the largest atomic number and therefore silicon has the smallest atomic radius because atomic radii decrease from left to right across a period.
Which is smaller O or O2?
O- has smaller size as it has only 9 e. Whereas O2- is larger because it has 10 e.
Why does ne have a smaller atomic radius than n?
Since Ne has the most protons out of the 3 ( and they belong to the same period, which means they have the same amount of occupied layers at ground state) , its electrons are pulled towards the nucleus by a greater force, resulting to them being closer to it. Hence, Ne has a smaller atomic radius.
What is the atomic radius of all the elements in order?
Atomic Radius of All the Elements (Complete Chart) Atomic number Elements Atomic Radius of Elements (pm) 6 Atomic radius of Carbon (C) 170 pm 7 Atomic radius of Nitrogen (N) 155 pm 8 Atomic radius of Oxygen (O) 152 pm 9 Atomic radius of Fluorine (F) 135 pm
Which is the smallest and largest element in the periodic table?
As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
What are the atomic numbers of the elements?
Atomic number Elements Atomic Radius of Elements (pm) 1 Atomic radius of Hydrogen (H) 120 pm 2 Atomic radius of Helium (He) 140 pm 3 Atomic radius of Lithium (Li) 182 pm 4 Atomic radius of Beryllium (Be) 153 pm 5 6 7
