The element with the atomic number 13 is aluminum.
Aluminum is an element with the atomic number of 13.Aluminum is an element. It's atomic number is 13.
is element
The element Bismuth (Bi) belongs to the Nitrogen family (Group 15). This means it has similar characteristics to other elements in this family. Bismuth is atomic number 83 and the last non-radioactive element.
Oxygen is the most abundant element in the earth's crust and is not in the boron family. Aluminum is in the boron family and is the third most abundant element in the earth's crust. Refer to the related link for a list of the 10 most abundant elements in the earth's crust and their percentages.
Aluminium or aluminum (they're the same element, just spelt and pronounced differently depending on where you are from)
aluminum
The oldest element in the boron family is boron itself, which has an atomic number of 5. Boron is followed by aluminum, gallium, indium, and thallium in the boron family.
In the periodic table of Mendeleev silicon is placed after aluminium.
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 of neutrons is irrelevant for determining the element. 13 protons makes it aluminum. (The isotope of aluminum with 13 neutrons is unstable and radioactive, with a half-life of about 720,000 years.)
The element with an atomic number twice that of aluminum (13) is magnesium, which has an atomic number of 12.
