How do you show configuration of potassium that hat the atomic number 19?
Asked in Science, Chemistry, Atoms and Atomic Structure
What role does the electron configuration of an element play?
it possibly shows how many shells an element has to show its atomic number ...
Which two consecutive elements show increase in atomic number and decrease in atomic mass?
this happens with argon and potassium, and also with cobalt nickel. fun stuff. ...
What does the atomic number show you about the element on the periodic table?
The atomic number is the number of protons present in the element.
Asked in Isotopes
How are isotopes the same and how are they different?
Isotopes have same number of electrons, same atomic no. but different mass no. They are from the same element like isotopes of carbon. They are not having same number of neutrons. They show same electronic configuration. ...
Asked in Periodic Table
How does the periodic table indicate the number of valence electrons?
Periodic table indicates the number of valence electrons.It show electron configuration of electrons.The last number of electron configuration represent number of valence electron. ...
Asked in Atoms and Atomic Structure
How do you find the number of protons in a nucleus?
Look at the atomic number. The atomic number show the number of protons and electrons. So for Oxygen, there are 8 protons, and 8 neutrons! = 0 ...
Asked in Atoms and Atomic Structure
What does a dot diagram and a atomic number have in common?
they both show particles but an atomic number is the amount of protons in the nucleus and a dot diagram is to show the bonding of atoms with electrons. and does not show the amount of electrons those atoms have but the valence electrons each atom has ...
What is the dot in the middle of a dot and cross diagram?
i need to know this information and much more information for school. and i wish you can help me on it. what does a dot diagram show? what are two things a dot diagram must show? how can the group number help in determining the number of valence electrons? what is true for the dot diagram for every element in a group? what is helium's dot diagram? why is helium's dot diagram different? what do electron configurations show? how is the...
How can you find the number of outer electrons?
To find the number of outer electrons in an element, or valence electrons, look on the Periodic Table of Elements. Look at the last number of the electron configuration. An element that has an electron configuration of 2-7 has 7 valence electrons. Link to a periodic table of elements with electron configuration: http://www.chemicalelements.com/show/electronconfig.html ...

Which two settings show the default value of VTP configuration on a Cisco 2960 switch?
revision number pruning mode
Asked in Chemistry, Periodic Table
Information can be obtained about an element by where it is located on the Periodic Table of Elements?
The atomic strucutre and the sub-atomic particle. It place is according to how many shells it has and how many electrons in its outer shell. A new row on the table show a new shell on the element. The atomic number( the bottom) show the number of protons the neuclus has, and the atomic number(top one) shows how many protons and neutrons the atom has together this can be used to see if an isotope is made ...
Asked in Atomic Mass
Carbon atom with atomic no of 6 and atomic mass of 12 considered isotopes of one another?
No. A carbon atom has both an atomic number and an atomic mass. All carbon atoms have an atomic number of 6. The most common carbon atom has an atomic mass of 12. See the Related Questions for more information about carbon, isotopes and atomic number and atomic mass. Go to Answers.com and punch in "carbon isotopes" and it will show you various isotopes and the atomic mass (u) associated with each (shown as isotopic mass). ...
Why are electrons and protons important?
They are important because electrons show the negative charge of the atom and protons show the positive charge of the proton. Also, the atomic number in an element is the number of protons it has. ...
Asked in Periodic Table
What info does the periodic table of elements show?
Each box on the periodic table of elements shows at least three things. The number at the top of the box is the atomic number of the element. The letters in the middle of the box are the chemical symbol for the element. Remember that capitalization matters when writing those symbols. The number at the bottom of the box is the average atomic mass of the element. More advanced periodic tables may contain information about electron configuration, common oxidation states, and number...
Asked in Elements and Compounds
Why do sodium and potassium have the same number of dots in their electron dot diagrams?
Electron dot diagrams show the number of valence electrons and whether they are paired or unpaired. One of the trends of the periodic table is that elements within the same group have the same number of valence electrons. Sodium and potassium are in the same group. ...
10 kinds of isotopes and their application?
Different atoms of the same element possessing different atomic masses but having same atomic number are known as Isotopes. Since the isotopic atoms have the same atomic number, they must contain an equal number of protons. As their atomic masses are different, there must be a difference in the number of neutrons they possess. They will show similar chemical properties but their physical properties will be different due to different masses. ...
