1几道英语化学题!1.how are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on the periodic table?2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the...
1.how are the atomic numbers and the atomic masses of the elements related to how the elements are arranged on the periodic table?2.how does the number of electrons relate to the arrangement what is the different in the number of electrons in a 3rd period element and the 2nd period ...
Every element has a unique atomic number. This is the number of protons in the nucleus of each atom. What is the atomic number of this helium atom? A neutral atom must have equal numbers of protons and electrons, so the atomic number of an element also gives the number of electrons. ...
Anatomic numberis the number ofprotonscontained within the nucleus of an atom. Each element on the periodic table has a different atomic number. Currently, the atomic numbers of known elements range from 1 to 118. Thenucleus of an atomcontains protons andneutrons. An atom's electrons are found...
Accordingly, the number of protons, which is always equal to the number of electrons in the neutral atom, is also the atomic number. An atom of iron has 26 protons in its nucleus; therefore, the atomic number of iron is 26 and its ranking on the periodic table of chemical elements is ...
atomic number- the order of an element in Mendeleyev's table of the elements; equal to the number of protons in the nucleus or electrons in the neutral state of an atom of an element number- a concept of quantity involving zero and units; "every number has a unique position in the sequ...
