Very roughly speaking yes. There's a little wiggle room in the middle right of the table, where as you move downward there's more of a tendency for them to form positive ions rather than negative ones, but in general (and certainly on the left side) the common oxidation states for the atoms in each period are similar.
Ye, it is correct generally but not obligatory.
Yes the chemical properties are usually similar for each group. For instance, the alkali metals (Group I) form singly charged positive ions, due to their same valency.
Yes.
Elements of group 1 readily form ions having a charge of +1.
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-.
The charge for all elements in Group 2A is +2.
All the elements in Group 2A (Mg, Ca, etc.). A charge of 2+ is acquired by these metals in order for a more stable state to be achieved.
Any member of the alkali metals group, such as; Lithium, Sodium, Potassium etc.
The charge of group 7A elements when forming ions is -1 (negative 1).
Elements of group 1 readily form ions having a charge of +1.
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-.
Group 1 elements are the alkali metals, which form ions wih a 1+ charge.
lose 2 electrons and form ions with a 2+ charge.
Transition elements are the major group of elements with this property.
Group that tend to form -1 ions include group VIIA
When group 2A elements form ions, they lose two electrons. Some examples of group 2A elements include radium and magnesium.
When group 1A elements form ions, they form cations with a +1 charge.
The charge for all elements in Group 2A is +2.
All the elements in Group 2A (Mg, Ca, etc.). A charge of 2+ is acquired by these metals in order for a more stable state to be achieved.
Elements in group one of the periodic table; Lithium, Sodium, potassium, rubidium, caesium and rubidium, will form ions with a positive charge of one.
