What is the atomic radius of aluminum?

Gallium is a non metal element. Atomic mass of it is 70.


Given any two elements within a group is the element with the larger atomic number likely to have a larger or smaller atomic radius than the other element?

The atomic radius decreases across a period from left to right and increases down in a given group. That means that since the lower the element is in a group, the larger the atomic radius will be. The atoms with the largest atomic radii are located in Group I and are at the bottom of groups.


How can you use the word atomic radius in a sentence?

Please tell me your atomicnumber.You just did 'use atomic number in a sentence' by putting this question on-screen.You could even read the above question and answers aloud, and you will have done it again.I just couldn't believe my eyes when I realized that an atomic number is revealed by the number of protons in the nucleus of an atom!"What is your atomic number?" is NOT a good pick-up line, unless you are speaking to a scientifically-minded person.The atomic number of Helium is 2."The atomic number of Sulfur is 16."(Note that atomic number means the number of protons in the atom, that's why the term proton number is interchangeable with atomic number.)See the related Wikipedia link listed below for more information:


Any element can always be identified by its?

The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.

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.

What is the element in period 4 with the smallest atomic radius?

The element in period 4 with the smallest atomic radius is argon. It has a smaller atomic radius compared to the other elements in period 4 because it is a noble gas with a full valence shell, resulting in a small atomic size.


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


Period 4 element with smallest atomic radius?

The period 4 element with the smallest atomic radius is chlorine, which has a greater number of protons in the nucleus pulling the electrons closer, making it smaller compared to other elements in the same period.


Which element has the large atomic radius?

Francium. The elements of the lower left hand side of the periodic table have the largest atomic radius. The upper right has the smallest.
