What elements properties follow a pattern that repeats?
If elements are arranged in the increasing order of their atomic numbers after specific intervals elements having same number of valence electrons lies in the same group which shows they have same chemical properties.
What elements have their first two letters as a symbol?
The symbols for elements have either one or two letters. If there are two letters, the first one is capitalized and the second one is not.
Isotopes of elements?
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
Give the letters of two elements in the same period?
Na, Mg -- also Al, Si, P, S, Cl, Ar
What are elements having same number of protons and neutrons called as?
Carbon Number of Protons/Electrons: 6 Number of Neutrons: 6
Is elements atoms?
Elements are made of atoms. Each element is made up of the same kind of atoms, having the same atomic number.
What is a isotonic?
atoms of different elements having same number of neutrons
Where are the isotopes of the same elements having different atomic masses placed in the periodic table?
same slot
Can elements have the same chemical symbol?
If you mean two different elements, no. That would defeath the purpose of having chemical symbols.
What elements properties follow a pattern that repeats?
If elements are arranged in the increasing order of their atomic numbers after specific intervals elements having same number of valence electrons lies in the same group which shows they have same chemical properties.
How did Mendeleev discover a pattern of repeating properties in elements?
Mendleef arranged the elements in the increasing order of their atomic masses due to which elements having same properties were placed in the same group and there were few exceptions.
Why do some symbols have one letter some have two letters and some have three letters?
Elements are give symbols consisting of letters, and these are related to the names of the elements (in some language at some date). There are 26 letters in many alphabets, but more than four times that number of elements. So it is necessary to use some mechanism to distinguish among elements with names that start with the same letter. Adding numbers is done to designate the number of atoms in a compound, the isotope, and so on. The best solutions is to use pairs of letters for most elements.
What are elements on the periodic table are grouped based on?
Group are based on similar properties. The elements having same chemical properties are grouped together.
Why is there more compounds than elements?
its the same like there are more words than letters and combo is more than none
What does the food waffle have in common with the verb waffle?
Very little, except for being spelled with the same letters and having the same pronunciation.

What elements have their first two letters as a symbol?
