is the nucleus in the centre of the atom

In 1936, Neils Bohr suggested that the nucleus might be like a droplet of dense liquid, composed of sub droplets of protons and neutrons. A uranium nucleus is spherical in shape. In this spherical nucleus, protons and neutrons are together because of the delicate bala..

An atom is made up of three particles, electrons protons and neutrons. Electrons have a negative charge and protons have a positive charge whereas neutrons have no charge. They are neutral. Due to the presence of equal number of negative electrons and positive protons the atom..

The nuclei of atoms is made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus ..

Specification of configuration of compounds with more than on chiral carbon such as tartaric acid can be done by a) Specifying the configuration about each of the chiral carbons and b) Numbering the chain of carbon atoms present to easily denote which configuration refers ..

This is the number of protons present in the nucleus or the number of electrons present outside the nucleus. It is denoted by the letter Z. Atomic number (Z) = Nuclear charge or number of protons (p) = Number of electrons ..

The number of protons or the number of electrons in an atom in its normal state is called the atomic number and is denoted by Z. The nucleus of every element contains Z protons and some number of neutron..

The number of protons or the number of electrons in an atom in its normal state is called the atomic number and is denoted by Z. The nucleus of every element contains Z protons and some number of neutrons. The electrons, having the same charge as a proton but of opposi..

Electrons cannot exist at a particular point or in a well-defined orbit (path), according to the above new approach called wave mechanics. This led to the concept of 'most probable regions'. We talk about 'certain regions in space around the nucleus called atomic orbitals, wher..

Structure of the Atom - Summary Atom is the smallest particle of an element, which maintains its identity throughout chemical and physical changes. Atoms are made up of three fundamental particles: electrons, protons and neutrons. Discharge tube experiments by William ..

The bond length increases with increase in the size of the atom. From the above values it is clear that the bond lengths for a given family increase with increase in atomic number. For example, C-C < Si-Si < Ge-Ge This is because with the increase in size of the atom..
