huh?
No. Pyromanium is not an element. I have never even heard of it. you might want to check if pyromanium even exists.
Yes, as it is nearer the left side of the periodic table.
Each row of elements on the periodic table is called (ironically) a period! If you want to know the specific elements, try using a search engine to look it up, as there are over 100 elements and the list is too extensive to write out here (when it's already detailed far better in other sites).
The elements in the periodic table are arranged so that there is an increase from left to right (such as atomic radius) and from up to down (such as atomic weight). The elements that have somehow similar properties (not always, mind you) are arranged in families (or columns, as you unappropriately name them).Hope this is useful.
Well, only 74% of elements are metals on the periodic table... If you want to also know the percent of metalloids and nonmetals u have the answers too. Non-metals: 15% Metalloids: 50%
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.
they will lose electron to form mono positive cation
Wikipedia, WolframAlpha etc. will all tell you information about elements.If you want something similar to a periodic table, there is something called the Chart of the Nuclides (google it) that is somewhat like a periodic table, except that it includes all isotopes of elements. Plenty of textbooks have tables of atomic data too that aren't necessarily in a periodic table.
When making his periodic table Mendeleev noticed some spaces where elements should be couldn't be filled. He didn't want to force elements that didn't belong there to go there, so he believed the spaces were undiscovered elements. He left the names blank but predicted their properties. Later the elements Mendeleev predicted existed were discovered.
Some questions about elements that you may want to explore include: What are the properties of different elements? How do elements combine to form compounds? What role do elements play in chemical reactions? How are elements organized on the periodic table?
There are 92 naturally occurring elements, with a total of 118 naturally occurring elements in the periodic table. Each element is composed of atoms with a specific number of protons in the nucleus that determines its identity.
Antoine Lavoisier determined that oxygen was a key substance in combustion, and he gave the element its name. He developed the modern system of naming chemical substances and has been called the “father of modern chemistry” for his emphasis on careful experimentation.
