What are the combining ratios of elements in group II with elements in Group VII of the periodic table?
The combining ratio for Group II elements with Group VII elements is 1:2. For example, calcium (Group II) will combine with chlorine (Group VII) to form calcium chloride with a ratio of 1 calcium atom to 2 chlorine atoms.
What four elements have chemical properties most similar to those of fluorine in column VII A?
Column VII A is an obsolete name; the official name of IUPAC is Group 17 (halogens group).
What group in the periodic table is referred to the halogens?
In the usual form of the periodic table in current high school textbooks, the halogens are in column 17. In older books, this column was often designated as VII.
What four elements have chemical properties similar to fluorine in column VII A?
The other four halogens in column VII A of a narrow form or column 17 of a wide form periodic table: chlorine, bromine, iodine, and astatine.
What liquid forms -1 ions when they combine with metals?
Atoms that form negative ions are non-metals. Non-metals that form ions with a charge of 1- are in Group VII, because they must gain one electron in order to achieve a full shell. In Group VII, the physical states of the elements changes from gas to solid down the group at room temperature. Fluorine and chlorine are gases, bromine is a liquid and iodine is a solid. Therefore, bromine is a liquid at room temperature that forms 1- ions when it combines with a metal.

What is the group that hydrogen is in?
Hydrogen is a non-metal; it's in group VII
What would the formula be for rhenium VII oxide?
The chemical formula for rhenium(VII) oxide is Re2O7. It is composed of two rhenium atoms and seven oxygen atoms.
Which atoms have the highest electronegativity on the periodic table?
Group 17 elements have the highest electronegativity out of which fluorine has the highest electronegativity.
Which element in group 7 is an orange liquid?
Elemental bromine is an orange liquid and is in group VII, the Roman equivalent to 7, in narrow form periodic tables. In the now more commonly used extended form periodic tables, in which columns are usually given Arabic numeral numbers, bromine is in column 17, and every element in column 7 in column 7 is a transition metal and is solid at standard temperature and pressure.
What special names are given to the group you group vii and group viii elements?
group 7 - halogens group 8 - noble gases
What group has the most non metallic metals on the periodic table?
Group VII and Group 8 ( the noble gases)
What famioly does phoshorus belong to?
Group VII, the Nitrogen Family
