Is Size Of nucleus same for all elements?
The atom with the smallest mass is the hydrogen atom; its mass is about 10-27 kg. The masses of other atoms go up to about 200 times this. The nucleus of an atom is about 10-15 m in size; this means it is about 10-5 (or 1/100,000) of the size of the whole atom.
Can two nuclei have the same radius?
Can they have the same radii and same nuclear density? If sum of the number of protons and neutrons in the two nuclie is same, they can have the same radii (∵r∝A1/3). However , nuclear density of the two nuclei will always be the same.
Do all elements have the same nucleus?
In other words, all atoms of the same element have the same number of protons. Furthermore, different elements have a different number of protons in their nuclei, so the number of protons in the nucleus of an atom is characteristic of a particular element.
How do you find the radius of a nuclei?
The radius of a nucleus, r, is approximately r = r0A1/3, where r0 = 1.2 fm.
Are nuclei and nucleus the same thing?
Nucleus (plural nuclei) is a Latin word for the seed inside a fruit. It most often refers to: Cell nucleus, a central organelle of a eukaryotic cell, containing most of the cell’s DNA.
Is nuclei and nucleus the same?
Which are nuclei of the same element?
Nuclei of the same element with different masses are called Isotopes .
What is the radius of A nucleus compared to an atom?
This is surrounded by electrons arranged in shells. The nucleus is tiny compared to the atom as a whole: the radius of an atom is about 0.1 nm (1 × 10 -10 m) the radius of a nucleus (1 × 10 -14 m) is less than.
What is the nuclei of an element?
The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.
What is the size of nucleus of different elements?
Nucleus of different elements are different and has unique composition. Size of nucleus is of an order of 10 -14 m. The particles protons and neutrons present in the nucleus are collectively called as the nucleons. The number of protons present in the nucleus of an atom is called the atomic number. It is denoted by the letter ‘Z’.
What is the radius of an atom?
•Atomic radius: distance between nucleus of an atom and its valence shell •Metallic radius: half the distance between nuclei of two adjacent, identical metal atoms Copyright McGraw-Hill 2009 19 •Covalent radius: half the distance between adjacent, identical nuclei in a molecule
Do all nuclei have the same density?
The average radius of a nucleus with A nucleons is R = R0A1/3, where R0 = 1.2*10-15 m. The volume of the nucleus is directly proportional to the total number of nucleons. This suggests that all nuclei have nearly the same density. Consequently, is nuclear density same for all elements? Nucleus consists of neutrons and protons.
