What has one valence electron and reacts with other elements?

Any element in column 1 of a wide form periodic table has exactly one valence electron and reacts with other elements.


The elements in group 7A have one valence electron true or false?

A valence electron, or valence electrons, are found in all of the elements. A valence electron is an electron located on the out most shell of an element (the valence shell). Most elements will have more than one valence electron. Oxygen, or O, has six valence electrons because its outer shell consists of six electrons.


How many valence electron level does an element have?

Except for elements 1 and 2, all elements are stable with how many electrons in their outermost (valence) level?


Are all elements with one valence electron conductive?

No. For example, Hydrogen is an element with one valence electron, but it is a non-conductive gas under standard conditions.

How would you find valence electrons in a periodic table?

To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.


How do you determine the number of valence electrons in an element?

To determine the number of valence electrons in an element, you look at the group number on the periodic table. The group number tells you how many valence electrons an element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
