What is the atomic radius of helium and how does it compare to other elements in the periodic table?
The atomic radius of helium is about 31 picometers. Helium has one of the smallest atomic radii among all the elements in the Periodic Table due to its small size and high nuclear charge.
What else can I help you with?
Is helium and argon the same?
No, helium and argon are not the same. They are two different elements on the periodic table with different properties. Helium is a noble gas with the atomic number 2, while argon is also a noble gas but with the atomic number 18.
The elements with the smallest atomic radii are found in the?
The elements with the smallest atomic radii are found in the top of the P block of the periodic table. Helium (He) has the smallest atomic radius. Francium, on the other side of the periodic table (very bottom of the S block), has the largest atomic radius.
What come first cotton ball iron helium rubber?
Helium comes first because elements are arranged by atomic number on the periodic table. Helium has an atomic number of 2, which is the lowest among the listed materials. Then comes cotton ball, rubber, and iron in that order.
What is the weight of helium?
The weight of helium is very light, as it is one of the lightest elements on the periodic table. Helium has a very low density and weight compared to other elements.

What element is 2 on the Periodic Table of Elements?
Helium (He) is the element that is number 2 on the Periodic Table of Elements. It has an atomic number of 2 and is a noble gas.
What is the second element on periodic table of element?
sodium is the element
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 atomic sign for helium on the periodic table?
The atomic symbol for helium on the periodic table is He.
What element is the lightest of the elements?
Hydrogen is the lightest of all elements. According to the Periodic Table, its atomic weight is 1.00794 u, even lighter than helium.
What is the biggest jump in atomic weights between consecutive elements on the periodic table?
The biggest jump in atomic weights between consecutive elements on the periodic table occurs between hydrogen (H) and helium (He). Hydrogen has an atomic weight of approximately 1.008, while helium has an atomic weight of approximately 4.0026. This significant increase is due to the addition of a neutron in the helium nucleus, which contributes to its higher atomic weight.
Hydrogen is before helium on the periodic table because the periodic table arranges elements by increasing .?
atomic number
What were the first elements that were found in the periodic table?
The first elements discovered and placed on the periodic table were hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium, and magnesium. These elements were identified based on their unique chemical properties and atomic structures.
Is organized by atomic?
If you are referring to the Periodic Table of the Elements, it is arranged by the atomic number of each element, increasing from Helium, which has an atomic number of 1 through Ununoctium, which has an atomic number of 118.
what elements have the smallest atomic number?
Look at the periodic table. Hydrogen at. # 1, Helium, at.# 2, Lithium, at. # 3 etc.
How many elements are there in the first period of periodic table?
There are 2 elements in the first period of the periodic table: Hydrogen and Helium.
Is helium and argon the same?
No, helium and argon are not the same. They are two different elements on the periodic table with different properties. Helium is a noble gas with the atomic number 2, while argon is also a noble gas but with the atomic number 18.
