-Periods: Horizontal rows in the periodic table. Elements in the same period have the same number of electron shells but do not necessarily have similar chemical properties. Hint: Consider how elements are categorized in the periodic table based on their electron configurations. ...
The electron configuration of iodine can be written as:- 1st shell: 2 electrons- 2nd shell: 8 electrons- 3rd shell: 18 electrons- 4th shell: 5 electrons (from the 5s and 5p orbitals) Thus, the complete electron configuration for iodine is:I: 2,8,18,18,7 Step 3: Identify the Shells...
What is the maximum number of electrons that can have the principal quantum number 3 in a given atom? For the n = 3 shell, what is the maximum number of orbitals available for electron occupation? What is the maximum number of electrons in an atom whose highes...
In an atom, what is the maximum number of electrons that can have a principal quantum number of n = 3? What is the maximum number of electrons that can occupy the 3rd electron shell? A. 2 B. 6 C. 10 D. 18 In a given atom, what is the largest possible number of 3p ...
Thus, atoms of the same element can have different mass numbers, and these are called isotopes. The weight of an electron is almost negligible. Thus, the atomic mass of an atom is almost the same as its mass number. History of Atomic Number We take the existence of atoms for granted –...
Re:Number of Electron Shells in an Element «Reply #1 on:March 13, 2005, 05:03:42 PM » look up the electronic configuration of Xe athttp://www.chemicalforums.com/index.php?page=periodictable any general chemistry textbooks will tell you the order of orbitals you should fill up to ...
The principal quantum number is defined as the number designated as the electron shell, where most of an atom's electrons are situated. In the periodic table, the principal quantum number is the row in which an atom has been placed. The top row of atoms has a principal quantum number of...
For an electron, what is the number of possible m values if the angular quantum number is l = 2? For a neutral atom of element 37, what would be the probable ground-state electronic configuration? In your expression for the configuration, list the subshells in order of filling, ...
Changing the number of ___ of an atom would change the chemical properties of the atom. a. neutrons b. protons c. electrons d. electron shells The determines the chemical properties of an element, e.g. it's ability to react wi...
In this lesson: understand what the noble gas elements are, where they are found on the periodic table, and why the noble gases are stable. Related to this QuestionWhich group of the periodic table contains atoms with a stable outer electron configuration? In which group...
