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.
protons and neutrons
One covalent bond is between iodine and hydrogen.
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.
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.
