The location of an electron within any specified element's atom is governed by using certain numbers. These are basically called quantum numbers. All the electrons are arranged in a regular manner in various orbitals.Answer and Explanation: ...
What is atom? Which of the following atoms contains only three valence electrons: Li, B, N, F, Ne? An element in its ground state has the following electron configuration: (Ne)3s23p2. What is this element? An element in its ground state has the following electron configuration: (Ar)4...

Since an atom contains equal number of protons and electrons, it has no overall charge: the positive charges on all the protons are exactly balanced by the negative charges on all the electrons. But sometimes an atom can gain or lose an electron to become what's called an ion. If it ...
Re: How to determine what an atom is depicted from image of its orbitals « Reply #3 on: November 18, 2020, 12:55:21 AM » Orbitals are mathematical functions. Atoms have electrons in their orbitals. You give no information about the number of electrons in the orbitals. So it's ...
Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom. Electrons are extremely lightweight and exist in a cloud orbiting the nucleus. The electron cloud has a radius 10,000 times greater than the nucleus, according to theLos Alamos National Laborat...
(i) 12. (ii) 2. (iii) Be. Because Be has two electrons in its valence shell. Given element also has two electrons in its valence shell. Since valence electrons determine the chemical property, hence the given element has same chemical properties
