Question

element in a period all the same number of ________.​

Answer 1

Answer:

All the elements in the period have the same number of atomic orbitals. For example, Every element in the top row (the 1st period) has one orbital for its electrons. All the elements in the second row (the 2nd period) has two orbitals for their electron.

Answer 2

Answer:

Elements in a period have the same number of shells

Explanation:

• Periods are elements that exist in horizontal rows.
• Elements of the same period have the same number of shells because electrons are added in the same shell of the element.
• Going across the period, each element has one more proton and is less metallic than its predecessor.
• All elements in a periodic table period have the same number of complete shells as well as the same valence shell.
• The number of shells grows in proportion to the atomic number.
• The period number shows the number of shells of the linked element, therefore moving from top to bottom in a group raises the number of shells by one and remains constant when moving left to right throughout a period.
• The value of n for the outermost or valence shell is indicated by the period in the table.
• The filling of the next higher main energy level (n=1,n=2, etc.) is related with each subsequent period in the periodic table.
• The number of elements in each period is clearly double the number of atomic orbitals available in the energy level being filled.
