Elements across a series have the same number of atomic energy levels. An elemental series is better known as a period.
good ??????????????????????????????????????????????
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
A. They have the same number of protons.B. They have the same number of orbitals.C. They have the same number of electrons.D. They have the same number of neutrons.
the period
Why not?If two atoms have the same number of protons, they're the same element. Therefore, unless they're electrically charged, they must have the same number of electrons as well. So the number of electrons in two different elements must be different if the atoms are electrically neutral.
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
good ??????????????????????????????????????????????
valence electrons, which determine their chemical properties and how they form bonds with other elements. This shared electron configuration gives elements within the same group similar reactivity and properties.
As you move across a period, elements have the same number of electron shells but different numbers of valence electrons. This leads to differences in reactivity and chemical properties across the period.
The rows going across the periodic table are known as periods and contain elements with the same number of electron 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.
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
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.
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.
A. They have the same number of protons.B. They have the same number of orbitals.C. They have the same number of electrons.D. They have the same number of neutrons.
Elements have the same number of protons in each atomic nucleus.
