How does the atomic radius change from left to right in Groups 1 and 2?
The atomic radius increases from top to bottom in groups 1 and 2 of the modern periodic table. This happens because the number of energy shells increase and are occupied by the increasing number of electrons. As the subsequent shells are completed they are located further from the nucleus due to the decreasing force of attraction between nucleus and the electrons. This leads to an increase in atomic radius. == == Atomic radius is a result of the completion of orbitals as atoms get heavier by adding neutrons and protons to the nucleus. The larger nucleus can hold more electrons. The cloud of electrons determines the atomic radius. Each completed orbital (S,P,D or F) takes up room. The higher orbitals have a greater radius . Unlike the old Bohr theory of atoms (little electrons in orbits around the nucleus), the new probability distribution interpretation of the electrons leads to spherical or hourglass shaped volumes.
In a sample of pure copper all atoms have the same what?
All atoms have atomic numbers which are the same and the atoms have the same number of electrons.
What happens when sulfur reacts with potassium?
Electrons move from the potassium atoms to the sulfur atoms.
The atomic number is equal to the numbers of?
The atomic number is the number of protons in the nuclei of the atoms of a particular element. The elements are arranged in increasing order of atomic number on the periodic table. In a neutral atom, the number of electrons equals the number of protons. However, the number of electrons is not the atomic number.
What is the relationship between mass number and atomic numbers?
Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
What happens to the atomic radius as the atomic number increases?
Going across a row in the peiodic table, the atoms have more protons and electrons causing a stronger attractive force, pulling the electrons closer to the nucleus, making the atomic radius decrease. As a new shell is added ( next row down) the atomic radius increases
What is half the distance from center to center of two atoms bonded together?
If the atoms are the same, it is the atomic radius.
What is the atomic radius of a chemical element?
The atomic radius, is the measured size of the atoms of a chemical element. Usually this is the typical distance between the nucleus and the boundary of the surrounding electrons.

Is the two atoms have same atomic radius?
Two atoms of same element (for a given isotope) are identical and hence have the same atomic radius.
What happens to the atomic size of the atoms as you go from left to right of the periodic table?
The atomic radius decrease from left to right in the periodic table.
Were on the periodic table would you find atoms with the largest atomic radius?
Atomic radius increases down the group. So larger atomic radius are present at the bottom.
How many electrons that each atom have?
each of atoms have electrons that equql to atomic number of that of atoms
What does Bohrs diagram represent?
it represents where the atoms, protons, Atomic Mass, atomic number, and electrons where they are located on the nucleus.
How do you rank configurations by atomic radius?
Nuclear radius increases as you go down and to the left on the periodic table due to effective nuclear charge. Bassicaly, it means that sheilding of electrons by larger atoms having more things in the way that blocks the ability of the nucleus to pull on the electrons, thus the electrons are able to be further from the nucleus and have a larger radius.
What does atomic radius means?
Atomic Radius means the size of the atoms, the distance from the atomic nucleus to the outermost electron orbital.
How is the radius of an atom related to the atoms attraction for outer level electrons?
As the radius of an atom increases, the attraction between the positively charged nucleus and the negatively charged outer level electrons decreases. This is because the outer level electrons are farther away from the "home base." So, as atomic size (radius) increases, the nucleus has less and less a hold on those outermost electrons. For this reason, cesium (Cs, atomic #55) has very large atomic size and very low electronegativity. Fluorine (F, atomic #9) has very small atomic size but large electronegativity.
