number of neutrons for potassium

The whole mass of an atom is due to the nucleus, which means that the nucleus must contain protons equal to the mass of the atom. As the number of protons is equal to the atomic number, the atomic mass should be equal to the atomic number. But for all atoms except hyd..

Atomic number of potassium is 19 and its electronic configuration is K L M N 1 8 8 1 Atomic number of calcium is 20 and its electronic configuration is K L M N 2 8 8 2 This abnormal behaviour can be explained as follows: It is found that shells have sub shells. The sm..

Nuclear Stability and Neutron/Proton Ratio - It has been found that the stability of nucleus depends upon its neutron to proton (n/p) ratio. A plot of N (the neutron number) against Z (atomic number or number of protons) show that for stab..

The nuclei of atoms are 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 is exactly equal to the ..

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 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 ..

The total number of protons and neutrons present in one atom of an element is known as its mass number. Mass number = number of protons + number of neutrons It can also be said that: Mass number = Atomic number..

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 is exactly equal to the n..

Oxidation Number and Nomenclature - When an element forms two monoatomic cations (representing different oxidation states), the two ions are distinguished by using the ending 'ous' and 'ic' at the end. The suffix 'ous' is used for the cation with lower oxidation state and the suffix 'ic' ..
