The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.

The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
How many valence electrons are in the dot structure or the elements in 3A?
The elements in 3A all have 3 valence electrons.
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
How many valence electrons can an atom have?
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
How many electrons are in the valence shell of all column 1 elements?
there are 36 electrons in a valence shell. -cmoney
How many valence electrons do transitions elements have?
How many valence electrons do transition elements have?
What happens to the reactivity of metals from left to right across the perriodic table?
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
How many valence electrons are in the dot structure or the elements in 3A?
The elements in 3A all have 3 valence electrons.
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
How many valence electrons does an element in group 4 have are they reactive?
All elements in group four have FOUR valence electrons. This is easy to remember because the group number located at the top of the periodic table of elements corresponds precisely in all cases to the experimentally observed number of valence electrons in the elements. It is also important to know that the elements in group eight (the inert gases) all have eight valence electrons, meaning that they can neither gain or lose electrons in the way of bonding with other elements, thus the maximum number of valence electrons any molecule can have is eight.
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.

How many valence electrons do each what elements have boron gold krypton and calcium?
Gold has 25 valence electrons
How many electrons are in the valence shell of all column 1 elements?
there are 36 electrons in a valence shell. -cmoney
How many valence electrons do alkali metal family members have?
The key to this answer is the phrase "valence electrons". Alkali metals are in the first column of the periodic table and include elements such as Lithium, Sodium and Potassium. These elements typically lose ONE electron when they participate in a chemical reaction, therefore they have ONE valence electron.
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
