Lower left corner and the upper right corner before the noble gases

Number of valence electrons

Explanation:

The most reactive elements are the most electropositive and electronegative elements.

Francium is the most reactive metal and flourine the most reactive non-metals.

Francium is the most electropositive metal and fluorine is the most electronegative non-metal.

Electropositivity is the ability of an atom to willingly lose its valence electrons. This is typical of metals.

Electronegativity is the ability of atoms to attract the shared electrons to themselves in a bond.

  • An element is more reactive than another based on the number of valence electrons it has.
  • The valence electrons determines how reactive an atom is or would be.
  • Elements that requires just one or two electrons to complete their octet would be highly reactive and dire need to find such electron.
  • Also, elements with just an electron above the stable configuration will easily want to lose it.
  • Elements with a complete configuration will  not be reactive.

The valence electrons are the electrons in the outer most shell of an atom used in chemical bonding.

What words can you spell isotherm periodic table
AlladinOne [14]

Explanation:

The periodic table of elements has a rich diverse number of elements. Every element on the table is arranged based on their atomic numbers into their respective groups and columns.

The coining of words from the table is done creatively by combining symbols of elements.

Here are some of the world list:

TaXEs  , TeAcH   ,TeAm  , TeTaNUS , CoW,,  CoVEr  COY

What characteristics do the elements in a group share? In a period, share?
Katyanochek1 [597]

Answer:

The elements in same period have same principle quantum number or energy shell.

The elements in same group shows similar chemical and properties.

Explanation:

Inn group:

The elements in same group i.e present in vertical column shows similar chemical properties.

The elements in same group having same number of valance electrons. while in chemical reaction bonds are break and formed and valance electrons are involved. That's why elements in same group having same number of valance electrons and shows similar chemical properties.

In period:

While as we move from left to right the number of valance electron increase by one in every element. But the electron is added in same shell which means that their physical and chemical properties are different but principal quantum number is same.
