Place the following atoms or ions in order of increasing radius O O2- S2- and Se2-?
O, O2-, S2-, and Se2-
O is smaller than O2- because O2- has 2 extra electrons but the same amount of protons as O, so they are held less tightly and the atom is bigger. Atom size increases as you move down the Periodic Table, so O2- < S2- < Se2-.

What is half the distance from center to center of two atoms bonded together?
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.
Is the two atoms have same atomic radius?
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.
Would the same behavior exist in atomic radius for the ions of atoms?
No, the behavior of atomic radius for ions of atoms would not be the same. When an atom gains or loses electrons to become an ion, its radius changes. Cations (positively charged ions) are smaller in radius compared to their parent atoms because they lose electrons, leading to increased effective nuclear charge pulling the remaining electrons closer. Anions (negatively charged ions) are larger in radius as they gain electrons, resulting in increased electron-electron repulsion and expansion of the electron cloud.
Which of the following decrease as you go from left to right on the periodic table?
The atomic radius decreases as you go from left to right. or atomic radius cation radius && anion radius -barbie=]
What is the relationship between the atomic radius and chemical reactivity of elements in the periodic table?
The atomic radius of an element is inversely related to its chemical reactivity. Smaller atomic radius generally leads to higher reactivity, as smaller atoms have a stronger attraction to other atoms and are more likely to form bonds. Conversely, larger atomic radius tends to result in lower reactivity, as larger atoms have weaker attraction and are less likely to form bonds.
In the alkaline-earth group atoms with the smallest radii?
Atoms with the smallest radii in the alkaline-earth group are found at the top of the group, such as beryllium. This is because as you move down the group, additional electron shells are added, increasing the atomic radius.

The atoms become smaller in atomic radius.
What is the relationship between the FCC lattice constant and the radius of atoms in a face-centered cubic crystal structure?
In a face-centered cubic crystal structure, the FCC lattice constant is related to the radius of atoms by the equation: (a 4 times sqrt2 times r), where (a) is the lattice constant and (r) is the radius of the atoms. This relationship helps determine the spacing between atoms in the crystal lattice.

Is it true Moving across a row of the periodic table the atoms tend to get bigger?
Yes, as you move across a row (period) of the periodic table from left to right, the atomic radius tends to decrease. This is due to the increasing effective nuclear charge, which pulls the electrons closer to the nucleus, making the atoms smaller.
Can give you some explanation about the structure of the atom esspecially about it's radius?
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.
