What are the two main differences in 1A and 7A elements?
The classification with 1A, 7A etc. is not recommended by IUPAC and is obsolete.The 1A elements are alkali metals, all solids; the 7A elements are the nonmetals (halogens). Halogens can be gaseous, liquids or solids at room temperature.
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
Characteristic of elements in group 7A?
They are Halogens
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
7 in 7A 2 in 7B The 7A are representive elements The 7B are transition elements

What other group on the periodic table is most likely to react with elements in group 1A?
If you meant to say "elements ARE most likely to bond with," which is probably what you meant, then the answer would be 7A(or 17), also called the Halogens. "Halogen" actually means "salt-forming." When you take a chlorine (7A) and sodium (1A), you end up with table salt! ---- In a nutshell, the answer is Group 7A, or 17.
What group does the alkaline earth metals belong to?
The alkaline earth metals belong to group 2A elements. The alkali metals belong to group 1A elements. The halogens belong to group 7A elements. The noble gases belong to group 8A elements.
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
What do group 7A elements become when they react with group 1A?
Atoms of column 7A become anions when they react with atoms of group 1A elements, which become cations. Both the cations and the anions are monovalent. The cations and anions together form an ionically bonded compound.
Are Group 7A elements the alkaline earth metals?
Group 7A are not metals.Alkaline earth metals refer to Group 2A.and group 7a is halogens which are non-metals
The Group 7A elements form ions with a charge of?
The charge of group 7A elements when forming ions is -1 (negative 1).
Consider the group 1A element sodium (atomic number 11) the group 3A element aluminum (atomic number 13) and the group 7A element chlorine (atomic number 17). These elements are in period 3. How are?
This is a consequence of the law of periodicity of chemical elements.
Characteristic of elements in group 7A?
They are Halogens
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
7 in 7A 2 in 7B The 7A are representive elements The 7B are transition elements
What are Element in group 1 to 7?
Group 1:Hydrogen (H),Lithium (Li), Sodium (Na), Potassium (K), Rubidium (Rb), Caesium (Cs) and Francium (Fr). Group7: Fluorine (F), Chlorine (Cl), Bromine (Br), Iodine (I) and Astatine (At)
What are the 4 main categories of elements found on the periodic table?
- The Group 1A elements are called alkali metals. - The Group 2A elements are called alkaline earth metals. - The nonmetals of Group 7A are called halogens. - The Group 8A elements are called the Noble Gases
