Which is bigger in size aluminum atom or chlorine atom?
The chlorine atom is bigger in size than the aluminum atom. This is because the atomic radius of chlorine is larger than that of aluminum due to the additional electron shells present in the chlorine atom.
Who has a larger atomic radius Be or O?
N-- Because it has less electrons, the proton pull is smaller on each individual electron, holding them closer to the nucleus and making the radius smaller
Why is the atomic radius of potassium larger than calcium?
Although they are all group I atoms, Na and K have a nuclear charge representative of s,p,and d electrons. Once you get to Rb the 4f sublevel comes into play along with the significantly increase nuclear charge. As a result, the does not increase as significantly as the Na and K.
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.
Does atomic radius increase left to right in the periodic table of elements?
Generally it decreases. There are a few exceptions: the noble gases tend to be quite a bit bigger than the corresponding halogens, and there's a smaller bump as you go from d-block elements to p-block elements.
When phosphorus becomes phosphide what happens to radius?
The radius of any anion is larger than the original neutral atom. So phosphide (P^3-) which as gained 3 electrons, has a larger radius than phosphorous (P).
Which is bigger in size aluminum atom or chlorine atom?
The chlorine atom is bigger in size than the aluminum atom. This is because the atomic radius of chlorine is larger than that of aluminum due to the additional electron shells present in the chlorine atom.
How do you arrange the following elements in order of increasing atomic radius from 1 (smallest radius) to 4 (largest radius). Sb As N and P?
N, P, As and Sb
What is p in p block?
Atomic radius increases down the group
How do you arrange the following elements Sb As N and P in order of increasing atomic radius from 1 (smallest radius) to 4 (largest radius).?
N (smallest radius) P As Sb (largest radius)
Which of the following has the smallest atomic radius P AL S Si Cl?
Atomic radius increases going down the periodic table and going from right to left, meaning that Fr (Francium) has the largest atomic radius and He (Helium) has the smallest. Therefore, Cl<S<P<Si<Al So the answer is Cl
What is the distance from the center of the nucleus of an atom to its outermost electron?
for hydrogen it is about 37 pico-meters. larger atoms (larger than H or He) have a second, or even 3, 4, 5, 6, or 7 orbitals of electrons. Francium, #87 has an atomic radius of 270 p-m. Much bigger, but way tiny compared to you.
What group is the p block in?
Atomic radius increases down the group
What element has the smallest atomic radius of all the p-block elements?
Fluorine has the smallest atomic radius of all the p-block elements. This is because as you move across a period from left to right, the atomic radius decreases due to increasing nuclear charge pulling the electrons closer to the nucleus.
Who has a larger atomic radius Be or O?
N-- Because it has less electrons, the proton pull is smaller on each individual electron, holding them closer to the nucleus and making the radius smaller
Why is the atomic radius of potassium larger than calcium?

What element have the smallest atomic radius?
Atomic Radius gets greater down the periodic table and gets smaller to the right in the periodic table. This means, in order of atomic radius, that the five smallest elements are Helium, Neon, Fluorine, Oxygen, and Hydrogen in that order.
