4. Calculate the Total Number of Electrons in the Ion X(−2): Since the neutral atom has 16 electrons and it gains 2 more, the total number of electrons in the ion X(−2) will be: 16+2=18 5. Determine the Electronic Configuration of the Ion X(−2): Now, we need to distr...
Each atom has an equal number of protons (+1 charge) and electrons (-1 charge), therefore the overall charge of the atom is 0, or 'neutral'. If one or more electrons are removed then the particle would be positively charged and if one or more additional electrons joined the particle th...
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...
Keith Cooper is a freelance science journalist and editor in the United Kingdom, and has a degree in physics and astrophysics from the University of Manchester. So how does nature build an atom? The basic picture is of a nucleus containing protons and neutrons surrounded by electrons that orbit...
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 ...

An element Z has atomic number 16. Answer the following questions on Z: State the formula between Z and Hydrogen. View Solution An atom of an element X has 2 electrons in its N shell. Write the formula of its chloride. View Solution An element X has atomic number 17 and has mass...
Atoms are the fundamental unit of an element. They consist of a nucleus and surroundingelectrons. When an atom has an incomplete electron shell, it is said to have valence electrons. When two or more atoms come together to share outer shell valence electrons, a chemical (covalent) bond is ...
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...
