The atomic number is unique on the element and can be used to identify the element. Knowing the atomic number helps us determine the atomic mass of the element since the number of proton and the number of neutrons are the same and almost has the same weight. The periodic table...
If an atom has 17 electrons, 20 neutrons, and 19 protons, what is its approximate atomic mass? What is the atomic mass of Silver (Ag)? Find the atomic mass and mass number of an atom with 6 protons and 8 neutrons. a) What does the average atomic mass of an element represent? b)...
With the change to the Firewall CSP, when any rule in the block is unsuccessful in applying to the device, all the rules from that same Atomic block that were applied successfully are rolled back. This behavior ensures the desired all-or-nothing behavior is implemented and prevents a partial...

The periodic table lists the atomic mass and molar mass of each element. The values are the same, but their units are different. Atomic mass has the units atomic-mass-units, or AMU. Molar mass is the mass of one mole of the element, which is the mass of Avogadro's number of atoms ...
The orientation of electrons of a neutral atom in orbitals is given by electronic configuration. Answer and Explanation: 1. The given electronic configuration of first atom is {eq}{/eq}. In this configuration, ...
