process of removing an electron from a stable nucleus

. It finds it in the water molecules, which dissociates into protons and oxygen gas. The P 7 0 0 chlorophyll molecule is oxidized and an electron is boosted to a primary electron acceptor from which it goes downhill to NADP. The electrons removed from P 7 0 0..

Nuclear - Binding energy - The sum of the individual masses of various particle in the nucleus must be equal to the nuclear mass. But this is not so in actual practice. The nuclear mass is somewhat less than the sum of the individual masses of various nuclear particles. The difference bet..

>d- Block elements are the elements of group 3, 4, 5, 6, 7, 8, 9, 10, 11 and 12 placed in the middle of the table. They are also known as transition elements. The inner transition or f-Block elements - lanthanides and actinides, are placed in two separate horizontal series at the bottom of the peri..

Nuclear energy is released when very small particles of matter split or combine. After the split or combination, they result in small particles or heavy particle. The rest of the mass is changed into energy. This process of changing mass into energy produces the energy. Energy can also ..

All the cells of an organism receive the complete set of genes (total information) present in the fertilized egg through mitotic divisions. However, cells of an early embryo lose the potential for the expression of all the genes through the processes of induction and repression, perhaps b..

. Nowadays other bombarding particles (i.e., projectiles) like protons ( 1 H 1 ), deutrons 1 H 2 electrons can be accelerated to very high speeds by fluctuating electric and magnetic fields in machines such as cyclotron, synchrotron etc. These high speed particles are more efficient in ca..

(called hydration energy) is released in the third step. This compensates the higher energy needed to remove electron in second step. The net effect is that it has greater tendency to lose electrons in solution than other alkali metals and the reaction: Therefore, lith..

="left"> Robert Brown described the nucleus in plant cells. 1838-39 Sehleiden and Schwann proposed the cell theory. 1840 Purkioje proposed the term 'protoplasm’ to the contents of the cell. 1855 Virchow suggested that cells arise from pre-existing cells by a process of cel..

Radioactivity Spontaneous emission of active rays by certain unstable elements. Three types of radiations are: (i) Alpha particles He 2 + ion (Helium nuclei). (ii) Beta - rays - consist of electrons. (iii) Gamma - rays - High energy electromagnetic rays. Emission of alpha part..

. At the receiver these variations are detected or demodulated i.e., the message is removed from the carrier. (Although the more precise terms are demodulation for the process and demodulator for the device, the terms detection and detector are widely used.) After reception and ..
