Atomic number stands for the number of protons or electrons present in an atom
i had the same question on my science homework!
It is a chemical element with atomic number 8.
Well, in science I am learning atoms. Element: Carbon ....... Symbol: C ...... Atomic Number: 6 ....... Atomic Mass: 12 Element: Argon ......... Symbol: Ar...... Atomic Number: 18 ..... Atomic Mass: 40
The number of neutrons in an atom is easily calculated by taking the mass number and subtracting the atomic number. Take for example, Uranium: the mass number on the periodic table is 238, while the atomic number is 92. Take the difference of 238 and 92 and that will be equal to the number of neutrons. 238-92=146
The atomic number of lithium is 3. Therefor there are 3 protons and neutron in the nucleus of lithium. Lithium also has 4 neutrons. atomic # = protons and neutrons neutrons = rounded atomic mass - atomic number Sources- 7th grade Acc. Science
The atomic number of titanium is 22. Titanium 119 is an isotope unknown to science
26 is the atomic number for Iron (Fe)
It means that 2 is calciums' mass number and atomic number
Radium is an element, atomic number 88.

i am pretty sure it is cobalt. atomic number is 27. it is a solid. it is a metal. its atomic mass is 58.933.

they can be very harmful , some people use science for explosion of atomic bomb which causes a great number of casualty!
