There are 12 such elements and they are hydrogen, helium, lithium, beryllium, boron, carbon, nitrogen, oxygen, fluorine, neon, sodium and magnesium.
The element with an atomic number lower than aluminum and in group 15 is phosphorus. It has an atomic number of 15, which is lower than aluminum's atomic number of 13.
The number to the lower right on an element symbol is the atomic number, representing the number of protons in the nucleus of an atom of that element. It does not indicate the number of atoms of that element in a compound; that information is conveyed through subscript numbers next to the element symbol in a chemical formula.
The element in Group 1A with a higher atomic number than chlorine but lower than bromine is iodine.
The atomic number is determined by the number of protonsin the nucleus of the atom.The atomic number is conventionally written to the lower left of the chemical symbol for the element, e.g. for oxygen and for copper:8O 29Cu
The atomic number is usually written to the lower left of the atomic symbol. The atomic mass is usually written to the upper right of the atomic symbol. So, carbon-14 would look like this: 6C14
The element with an atomic number lower than aluminum and in group 15 is phosphorus. It has an atomic number of 15, which is lower than aluminum's atomic number of 13.
Element S has similar properties to element T but has a lower atomic number.
Examination of a periodic table shows that the element is potassium.
The number to the lower right on an element symbol is the atomic number, representing the number of protons in the nucleus of an atom of that element. It does not indicate the number of atoms of that element in a compound; that information is conveyed through subscript numbers next to the element symbol in a chemical formula.
Generally, any element with a lower atomic number.
The element in group one with a higher atomic number than chlorine but lower atomic number than bromine is iodine. Its atomic number is 53, which is greater than chlorine's atomic number of 17 but less than bromine's atomic number of 35.
The element in Group 1A with a higher atomic number than chlorine but lower than bromine is iodine.

Because the periodic table is organized by atomic number, not by atomic mass. The general trend in the periodic table is a higher atomic mass as you go up atomic number, but there are exceptions.
The atomic number is determined by the number of protonsin the nucleus of the atom.The atomic number is conventionally written to the lower left of the chemical symbol for the element, e.g. for oxygen and for copper:8O 29Cu
You think at fluorine (F).
