What else can I help you with?
Which block in the periodic tabe contains the alkali metals?
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
By what property did Moseley suggest that the periodic tabe be arranged?
After atomic numbers Henry Moseley supported the arrangement of periodic table of Mendeleev after atomic numbers and properties by a strong physical conception: study of the lines of X-ray spectra of chemical elements. It is a true relation between atomic numbers of elements and the wavelenghts of the characteristic X-ray lines.
Who prepared the modern periodic table?
I am thinking either Dimitri Mendeleev or Henry Mosely
What elements from the periodic tabe are in foods?
Elements commonly found in foods include carbon, hydrogen, oxygen, nitrogen, phosphorus, sulfur, potassium, calcium, magnesium, sodium, and iron. These elements play essential roles in the structure and function of biological molecules, such as carbohydrates, proteins, and fats, that make up our food.
How can you determined the number of valance electrons by looking at the periodic table?
Elements are located on the periodic table based off of their atomic number, but the vertical columns they are in (groups) show how many valence electrons they have. If an element were in Group 3 of the periodic table, it would have 3 valence electrons, and so on. This doesn't apply to the Transition Metals, so one should skip straight to Group 14, where the elements all have 4 valence electrons. Group 15 has 5, Group 16, 6, etc. The one exception to this is Helium, which is in Group 18 but only has 2.
Is the there such thing as Ba2 from the periodic tabe?
No - Ba is from the periodic table though.
How many protons aluminum have?
Aluminum contains 13 protons. It practically says so on the periodic tabe of elements because it's #13
Which block in the periodic tabe contains the alkali metals?
The Alkali Metals are the first column of the periodic table, except for Hydrogen.
How are groups in the periodic tabe arranged?
It's Is Arranged By Matals, NonMetals,Matalliods And Moble Gases
What is the periodic tabe arranged according to?
Atomic number A.K.A.: the number of protons in the nucleus of an atom of each element.
Why is the symbol U used to represent uranium on periodic tabe?
Uranium starts with letter U. So, its symbol is U.
