All lawrencium atoms have 103 protons in their nuclei, independent of the isotope of lawrencium in question. This is because the presence of 103 protons in the nucleus defines an atom as lawrencium, and changing the number of protons will change the element of the atom....
The most basic method would be to refer to the atomic configuration of an element and simply count the electrons in the outermost shell. However, this would be an extremely laborious task, as we may have to dig through textbooks to find configurations we do not know. However, there’s...
How to use a balance to find the mass of an object? Explain.Given that fluorine has an atomic number of 9, how are electrons placed into the orbitals? In what sense is the outer electron shell incomplete?An element has 43 protons an...
Anti-matter, it’s worth mentioning, is (presently) an absurd thing to build a weapon with. Considering that it takes the energy of a small town to run a decent particle accelerator, and that a mere hundred million anti-protons have all the destructive power of a single drop of rain, i...
Atomic number (number of protons in the nucleus): 26 Atomic symbol (on the Periodic Table of Elements): Fe Atomic weight (average mass of the atom): 55.845 Density: 7.874 grams per cubic centimeter Phase at room temperature: Solid Melting point: 2,800.4 degrees Fahrenheit (1,538 degrees Ce...
