How do you name the elements of the periodic table?
There is no need to name them. They have already been named
How many neutrons protrons nd electrons are in boron?
Look on a periodic table of the elements. If you can't figure it out from there, you don't really need to know.
Why do we need to study the arrangement and trends of elements in the periodic table?
It is easier to study the properties of elements if they are arranged properly.
How do new elements get added to the periodic table?
PeuPeuKarlrulez777:they need to be discovered somewhere in the world
Why it was needed to develop the periodic table?
The elements with same properties need to be grouped together. So that it is easier to study the elements
Why is the periodic table is important?
The periodic table is important because the world we live in is made up of chemicals and chemical reactions. To understand these reactions and continue to exist, we need to have the information at our fingertips and organized in an efficient way. The periodic table of elements is a fabulous way to organize and understand elements that make up everything. Chemical reactions and elements affect the way we live. The periodic table is organized so people can understand the properties of certain elements (molar mass, electronegativity, bond enthalpies, etc.).
What elements are not on the periodic table?
you will find almost everything about the element in the periodic table like its atomic mass and its atomic number, chemical affinity also its electronegative but you wont find when the element was discovered or weather it is found in free state or oxides in nature
How do you identify What is gas on the periodic table?
The periodic table itself will not tell you if an element is a gas or not. All elements have a melting point and a boiling point. For this information you need to look at a table of the PROPERTIES of the elements. However, all the elements in column 18 and many of the elements towards the top of column 17 and to some extent 16 are gasses at room temperature, as are all the elements in row 1.
How do you find the atomic mass number?
The atomic number is equivalent to the number of protons in the nucleus. See the Periodic Table of elements at the link below.
Why did Dmitri mendeleev reverse the order of some elements in the periodic table?
He was bold enough to reverse the order of some pairs of elements and to predict that their atomic masses were incorrect. Some of these predictions were correct, but others were not, because we now know that the fundamental basis of the periodic table is atomic number rather than atomic mass.
How is the no of proton determined in the proton?
You need to clarify this question. Do you mean, "How is the number of protons determined in the periodic table of the elements?"
What is the difference in the modern periodic table and Mendeleev's table?
The periodic table is now complete and can be displayed using the integral atomic numbers. In Mendeleev's time there were still unknown elements. In fact, one of the primary uses of his table was to predict the properties of elements that had not yet been isolated. (His 1869 table included speculative names for some expected elements.) -- In Mendeleev's periodic table, transition elements were placed in another group. --In Mendeleev's periodic table, noble gases were written on left side. In the modern periodic table, noble gases are written on right side.
