Elements in the same period have similar properties?

Answer 1

Elements of the same period have the same number of electron shells; with each group across a period, the elements have one more proton and electron and become less metallic.

Hope this helped you with your homework. :P

Answer 2

All the elements in the Periodic Table have the same general make up... that is, they are all made up of three things:protons, neutrons and electrons, although apart from that. Then they all simply differ in the ratio.

Hope that helps :)

Answer 3

Elements in the same period all have the same...number of valence electrons. Roughly speaking, it means atoms of that period have the same number of electrons available to interact with other atoms. This is more important for those elements filling their s and p orbitals which are drawn to the number of electrons of the nearest noble gas in the far right column, and then form ionic bonds (so H with 1 electron and Na with 11 electrons would each like to lose 1 electron <giving it a net positive charge> to get to the 2 electrons of He and 10 electrons of Ne respectively; while O with 8 electrons and S with 16 electrons would each gain 2 electrons <giving it a net negative charge> to get to the 10 electrons of Ne and 18 electrons of Ar respectively). In contrast, those elements in the middle of the table collectively called the transition elements, which are generally filling their f orbital, are not strongly drawn either direction and tend to form metallic bonds where all electrons are shared collectively.

Answer 4

Elements in the same period have the same number of shells of electron.

Answer 5

The elements in a period have the same number of atomic orbitals.

Answer 6

Elements in same period have same shells. The number of shells for elements in same period are same. The elements are arranged in order of increasing atomic number.

Answer 7

The number of valence electrons

Answer 8

the same number of electron shells
