It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, structure, behaviour, and changes that occur when they interact with other things. The quantum mechanical approach is currently used...
Black hole is defined to be a star which has a radius less than it’s horizon size. That is, the star is completely inside it’s event horizon. We show in this work that there is a solution of Einstein equation with matter corresponding to such an object. Penrose singularity theorem (...
Because protons are units of matter, atomic numbers are always whole numbers. At present, they range from 1 (the atomic number of hydrogen) to 118 (the number of the heaviest known element). As more elements are discovered, the maximum number will go higher. Theoretically, there is no maxi...
This is an ionic bond- the focus of this video. I started with this introduction to put ionic bonds into perspective and to remind you that all chemical interactions are almost always on a spectrum. So while it is useful to learn the details and specifics of ionic bonds, it’s good to...
State what is apomixis. Write its significance. How can it be commercially used ? View Solution What is radius ratio ? What is its significance in case of ionic crystals? View Solution What is a testcross? What is its significance? Give the phenotypic ratio of the testcross made between ho...
How does the reactivity of Magnesium Atoms compare to Magnesium Ions? Magnesium Atoms are more reactive than Magnesium Ions, which are more stable. 3 How does the size of a Magnesium Ion affect its properties? The smaller size of the Magnesium Ion affects its ionic radius and chemical reactivit...
