Uranium and plutonium.
Atomic Mass is the no. of protons+no. of nuetron
Both uranium and plutonium were used extensively to make the first two atomic bombs, dropped on Hiroshima and Nagasaki, respectively.
atomic mass is the no. of protons+no. of nuetron
An element with atomic number 7 (nitrogen) can make a maximum of 3 covalent bonds, while an element with atomic number 16 (sulfur) can make a maximum of 2 covalent bonds. Therefore, when they combine, they can form a total of 5 covalent bonds between them.
protons, no. of protons is equal to the atomic number of an element.
The element with an atomic number of 8 is Oxygen. It has 2 electrons in the first shell and 6 in the second, leaving a valence of 2. Oxygen, therefore, can form covalent bonds with only two Hydrogen atoms. This is also known as water.
Hydrogen. It has one proton and one neutron--you can't make an atom lighter than that.
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
first of all, atoms are not elements. they are microscopic little organisms in which make up the earth. second, next i believe comes protons, electrons, neutrons, and so on, until something is in the center which science hasn't even discovered yet, but its the answer to the world i believe.
One covalent bond is between iodine and hydrogen.
protons and neutrons
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
