Concept explainers
a.
To determine:
The number of electron in outer energy level and the group number of magnesium.
Introduction:
In the molecular or atomic orbitals the electrons of an atom or molecule is distributed. This distribution of electrons is called as the electronic configuration of the atom or molecule. It is used to show the orbitals of an atom in its ground state. The valance electrons are those which are present in the outermost principle energy level.
b.
To determine:
The number of electron in outer energy level and the group number of chlorine.

- How many valence electrons are needed to complete the outer valence shell of sulfur? a. 1 b. 2 c. 3 d. 4arrow_forwardA combustion reaction involves the reaction of a substance with oxygen gas. The complete combustion of any hydrocarbon (binary compound of carbon and hydrogen) produces carbon dioxide and water as the only products. Octane is a hydrocarbon that is found in gasoline. Complete combustion of octane produces 8 L of carbon dioxide for every 9 L of water vapor (both measured at the same temperature and pressure). What is the ratio of carbon atoms to hydrogen atoms in a molecule of octane?arrow_forwardThe contributions of J. J. Thomson and Ernest Rutherford led the way to todays understanding of the structure of the atom. What were their contributions?arrow_forward
- We have seen that the reactivity of an element is determined by its electron configuration. What is the electron configuration of the ion Cl-? (Hint: You must add one additional electron beyond the number of electrons that chlorine would normally have.) How does its reactivity compare with neutral Cl? How would the reactivities of Na and Na+ compare?arrow_forwardHow many valence electrons are in each element of problem 28?arrow_forwardThe noble metals gold, silver, and platinum are often used in fashioning jewelry because they are relatively .arrow_forward
- What makes a carbon atom different from a nitrogen atom? How are they alike?arrow_forwardThe contributions of J. J. Thomson and Ernest Rutherford led the way to todays understanding of the structure of the atom. What were their contributions?arrow_forwardWrite electronic configuration and answer the following: a. How many total s electrons are found in magnesium? b. How many unpaired electrons are in nitrogen? c. How many subshells are completely filled in Al?arrow_forward
- Look at the periodic table and tell how many electrons are in the valence shell of the following elements: a. element number 35 b. Zn c. strontium d. the second element in group VA (15)arrow_forwardWithout consulting your textbook or notes, state as many points as you can of Dalton’s atomic theory. Explain in your own words each point of the theory.arrow_forwardWhat is meant by anuclear atom? Describe the points of Ruth erford’s model for the nuclear atom and how he tested this model. Based on his experiments, how did Rutherford envision the structure of the atom? How did Rutherford’s model of the atom’s structure differ from Kelvin’s “plum pudding” model?arrow_forward
