the atomic number or # of protons in an atom
See the legend of your periodic table; a general rule don't exist.
Cu appears above silver in periodic table. It is placed in group 11 and period 4.
the number above the symbol is the atomic....... of that element.
You would get Sodium Chloride and Bromine. This is because Chlorine is a more reactive group 7, (halogen), element that bromine, we know this because it is above bromine in the periodic table group, it is therefore more electronegative. When the reaction occurs, the Chlorine displaces the Bromine and the solution turns brown.
Boron is a chemical element with symbol BIts atomic number is 5.It is a pure solid at room temperatureIts melting point is above 2000 degrees centigrades
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
The Atomic Number Is Located On The TOP Of The Element Symbol. So Example. 14<ATOMIC NUMBER> Si<Symbol> 28.086<Atomic Mass> Silicon <The Name> This Is The Correct Order Of An Element That Should Be Labeled.
Appears directly above sodium
There is no element above oxygen.
The number listed above the symbol of an element on the periodic table is the element's atomic number.
I and my colleagues can look at our periodic tables in micro-seconds. We'd still, wonder: What's your point?
tantalum atomic number 73
Tantalum (Ta)
if you look @ the periodic table, you will find the tiny # above the element... that is its atomic #.
if you look @ the Periodic Table, you will find the tiny # above the element... that is its atomic #.
if you look @ the periodic table, you will find the tiny # above the element... that is its atomic #.
Oxygen has an atomic number of 8, not 6. The number above an element on the Periodic Table generally is the atomic number. Carbon has an atomic number of 6.
If you look at the periodic table, Lithium (Li) is in the first column, group 1A, under Hydrogen, and above Sodium (Na). These elements are typically "electron donors" to fill out their electron shell. So, Lithium, Hydrogen, and Sodium all would typically ionize with +1 charges.
Lithium and potassium has same properties as sodium.They are alkali metals.They are placed in group-1.The elements of the same group have same chemical properties. Li and K are the elements above and below Na in the period. So they have same properties as sodium.
