Why do the elements in group 7 form ions with a negative charge?

Because the halogens are all diatomic. They only need one more electron to achieve a stable valence shell so they often get it from other radicals of the same element. Hence, you don't find F, Cl, or Br in nature. You find F2, Cl2, Br2.

Do elements in group 1 readily or rarely form ions?
Elements of group 1 readily form ions having a charge of +1.
When an atom becomes on ion with a two-charge the atom?
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
Elements on the RIGHT side of the periodic table form what kind of ions?
a negative charge
Shared when elements combine to form a compound?
Electrons are shared when elements combine to form molecules. These are subatomic particles with a negative elementary electric charge.
What is the charge for elements in group IIA?
The charge for all elements in Group 2A is +2.
The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
What group of elements tends to form negative ions that have a -1 charge?
Group that tend to form -1 ions include group VIIA
Do elements in group 1 readily or rarely form ions?
Elements of group 1 readily form ions having a charge of +1.
When an atom becomes on ion with a two-charge the atom?
The group 2 elements form ions with a 2+ charge. For example, Mg2+ and Ca2+. The group 16 elements form ions with a 2- charge. For example, O2- and S2-.
What type of ions do the elements of group 1 form?
Group 1 elements are the alkali metals, which form ions wih a 1+ charge.
Elements on the RIGHT side of the periodic table form what kind of ions?
a negative charge
When group A elements form ions they?
lose 2 electrons and form ions with a 2+ charge.
What kind of elements can form ions with more than one charge?
Transition elements are the major group of elements with this property.
Shared when elements combine to form a compound?
Electrons are shared when elements combine to form molecules. These are subatomic particles with a negative elementary electric charge.
When group 2a elements form ions what happens?
When group 2A elements form ions, they lose two electrons. Some examples of group 2A elements include radium and magnesium.
Which element forms an ion with a charge of negative one?
The elements in Group 1A all form ion with one positive charge. This group is collectively knows as the Alkali metals. They are Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. Hydrogen ions also can have a positive one charge, but it may, as easily, have a negative one charge.
What are the charges of ions in group1A?
When group 1A elements form ions, they form cations with a +1 charge.
