Aluminum was discovered in 1825 by Hans Oersted. It has a period number of 3, group number of 13, atomic number of 13, and block number p.
Aluminum has its electrons in three different energy levels. Therefore it is in third period. As it has three valence electrons, it is located in group 3.Aluminium is found in group-13. Its period umber is 3. Its atomic number is 13.Aluminium is a metal element. It is in the 13th group of the periodic table. And it belongs to the 3rd period.
Barium, atomic number 56, is in group 2 of period VI (six) in the periodic system.
A lot of numbers can be unlucky, depending on which period of time you are asking about, or what background you have. The most common unlucky numbers are 13, 666 (the number of Satan) and 4 - in Greek Mythology, the lucky number was 3 so 4 was an unlucky number.
Boron, atomic number 5, is a Group 13 element, in Period 2, in block p.
Boron is the element. Its symbol is B.

Indium in the periodic table: group 13, period 5, atomic number 49.
13 protons an easy way to remember what number of protons an element has is APES. A-atomic number, P-protons, E-electrons, S-same, so the atomic number and the numbers of protons and electrons are the same number
the chemical element of atomic number 13, a light silvery-gray metal.
13% = 0.13
Yup!! it sure is!! It is a metalloid and is found in group 13, period 2, and block p with an atomic number of 5.
