What is the Atomic weight of the Oxygen?
The atomic weight is 15.9994 (slightly less than the atomic number 16).
What is the atomic number and atomic mass of this element?
Atomic number is the number of protons. Atomic mass is (mostly) the sum of the masses of the protons and neutrons (more or less).
What is the new element formed after the alpha decay occurred?
AlphaThe atomic number goes down by two and the atomic mass number goes down by four.Beta-The atomic number goes up by one and the atomic mass number stays the same.Beta+The atomic number goes down by one and the atomic mass number stays the same.
What is one less proton than argon?
Chlorine, with the atomic number 17 has one less proton than argon, with the atomic number 18. The atomic number is the number of protons.

What is the lowest atomic number in the periodic table?
Atomic number: The number of protons in an atomic nucleus. (http://www.answers.com/topic/atomic-number) So the lowest atomic number is 1, which is hydrogen, as you cannot have an element with less than one proton.
The atomic mass of iodine is less than the atomic mass?
The atomic mass of iodine is about 126.9 g/mol, which is indeed less than the atomic mass of many other elements. This low atomic mass for iodine is due to its position in the periodic table and the number of protons and neutrons in its nucleus.
Boron is one block to the left of carbon in the periodic table the atomic number of carbon is 6 the atomic number of boron is?
The atomic number of boron is 5, one less than the atomic number of the atom in the block to its immediate right.
An atom with more or less neutrons is called a?
atomic number
What element in group one has a higher atomic number than chlorine but lower atomic number than bromine?
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.
