What else can I help you with?
What are the names symbols and atomic number of the top four elements in group 1267?
Group 12: Zinc (Zn), symbol Zn, atomic number 30 Group 13: Aluminum (Al), symbol Al, atomic number 13 Group 14: Silicon (Si), symbol Si, atomic number 14 Group 15: Phosphorus (P), symbol P, atomic number 15
What group does ununtrium belong to?
Ununtrium belongs to the group of elements known as the transactinides. These elements are part of the periodic table's seventh period and are characterized by their high atomic numbers and unstable radioactive properties.
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
How do the atomic numbers of the elements within each of Groups 1 2 and 13 to 18 of the periodic table vary?
Mendeleev's Periodic Table -- the reason for periodicity -- is explained by the arrangement of the electrons around the nucleus. *Read your chemistry book* :D
What does Al stand for on the periodic table of elements?
Al stands for Aluminium in the periodic table.It has atomic number 13 and belongs to group 13.
Oxidation number for first 20 elements?
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
The atomic charges of each group?
There's no charge within the atom of each group since there is a same number of electrons (negatively charged) and protons ( positively charged). The charge does not change unless after ionic bonding. The atomic charge changes depending on the reaction.
How is boron different from other elements in group 13?
Boron is the only element in group 13 that is a metalloid, meaning it shares properties of both metals and nonmetals. It has a unique structure due to its small atomic size and high ionization energy compared to its group members. Boron also forms covalent compounds instead of ionic compounds like other group 13 elements.
What is atomic mass number of elements?
13
What element has an atomic number lower than that of aluminum less valence electron than the the group 16 elements?
Nitrogen
How many protons does the element have in group 13 and the 3rd period?
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
What si the numbers for Aluminium?
The atomic number for aluminium is 13.
