Explain the relationship between atomic structure and the periodic table?

Answer 1

There are three main relationships that can be observed when linking element's structure to their position on the Periodic Table: * The group number represents the number of valence electrons in an atom. Example: lithium is in group 1, so it has one valence electron; calcium is in group two, so it has two electrons in its outer shell. * The horizontal period on which an atom lies equals the number of electron shells it contains. Example: lithium is in the second period, so it has two shells; calcium is in the fourth period, so it has four electron shells. * Generally speaking, as you read left to right along the table, the atomic number goes up by one.

Answer 2

Them atomic number of the atom, or the number of protons it has increases

has you go from left to right, and up to down,

so Neon has more protons then Lithium

and Sodium has more protons then Neon and Lithium.

Answer 3

An atom's atomic number (number of protons in its nucleus) determines which element it is, and where it is located on the periodic table. The elements are arranged in order of increasing atomic number on the periodic table.

Answer 4

To understand the following explanation, you'll need to know this:

GROUPS are the vertical columns in the Periodic Table

PERIODS are the horizontal rows in the Periodic Table

Group Number affects the number of electrons in the outermost shell. For example, if an element is in Group 2, it will have 2 electrons in its outermost shell!

Period Number affects the number of shells in an atom. For example, if an element is in Period 3, it will have 3 shells!

Hope this helped you. (:

Answer 5

Elements are listed on the periodic table by atomic number. That is the number of protons in one atom of the element.

Answer 6

each and every element in periodic table is considered as one atom

Answer 7

I is set up by the atomic number, so as it increases, the element will be set where the number belongs like a number like. For example, K is 19, so it will go in the 19th spot

Answer 8

Each chemical element has a specific place in the periodic table of Mendeleev depending on his number of protons (atomic number).

Answer 9

The periodic table is arranged according to the atomic number of elements. The atomic number is the number of protons.

Answer 10

The atomic number is equal to the number of protons in the atomic nucleus.
