Question: How many inner, outer, and valence electrons are present in an atom of iron (Fe)? (a) 18, 2, 6 (b) 20, 8, 8 (c) 20, 2, 8 (d) 18, 6,2 (e) 18, 2,8 Iron: Iron is a very crucial mineral that is required by...
The atom is the smallest representative unit of a single chemical element and it contains some numbers of protons, neutrons and electrons. The number of protons for an element is fixed and represented by its atomic number. The number of neutrons can vary, which is the basis for isotope...

To determine how many electrons are present in an atom with an atomic number of 20 and a mass number of 42, we can follow these steps:1. Understand the Atomic Number: The atomic number of an element is defined as the number of
Since the atom is neutral, the number of electrons is equal to the proton number. There are 46 electrons in aPdatom. Example 3 How many electrons does aP3−ion have? Step 1:Identify the proton number, also called atomic number, of the element on the periodic tabl...
Atoms are in your body, the chair you are sitting in, your desk and even in the air. See more nuclear power pictures. It has been said that during the 20th century, man harnessed the power of the atom. We made atomic bombs and generated electricity by nuclear power. We even...
Each electron in an atom is described by four different quantum numbers. The first three (n, l, ml) specify the particular orbital of interest, and the fourth (ms) specifies how many electrons can occupy that orbital. Principal Quantum Number (n) ...
The metaphor was drawn from the orbital trajectory that electrons follow. While circling the same atom's nucleus their trajectories invariably overlap. In my mind, the college campus served as that nucleus. With this knowledge, I could stand back and watch a shell route collision moment form. ...
