They don't have the same number. that's what makes thme all different
Valence orbitals
Valence eletrons
valence electrons
Valence electrons.
No two different elements can have the same atomic number.
The number of elements that contain the same type of outer electrons as sodium is 11.
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
The elements in the same group have the same number of valence electrons and hence similar chemical and physical properties.
The valence electrons for elements in the same group stay the same, since the number of valence electrons corresponds to the group number.
Elements across a series have the same number of atomic energy levels. An elemental series is better known as a period.
Assuming that series is used the same way as group in the periodic table, elements in the same series have the same number of valence electrons.
shells
In a series circuit, current will remain the same through all elements, and the voltage drop across elements will vary. So the answer is: it doesn't.
Electron shells
Elements in the same period have the same number of electron shells, moving across a period (progressing group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
Electron shells
The difference between a series and parallel circuit is that a series circuit is connected in such a way that the same current intensity flows through the elements while a parallel circuit is connected in such a way that the same potential appears across their terminals.
The elements in a group do not have the same number of shells, however, the elements in a horizontal row do have the same number of shells.
No, none of two elements in any group have the same number of neutrons. But there are such elements across a period, and they are known as isotones. Some examples are; carbon-12 and nitrogen-13 oxygen-18 and fluorine-19 phosphorus-31 and sulfur-32
All elements in the same group have the same number of valence electrons.
Elements have the same number of protons in each atomic nucleus.
