The Group 7 elements, also known as the halogens, share several similarities: they are all nonmetals, have high electronegativities, form ionic compounds by gaining one electron to achieve a full outer shell, exhibit similar chemical reactivity, and exist as diatomic molecules in their elemental form. Additionally, they all have seven electrons in their outer shell and tend to form -1 oxidation states in compounds. They also have similar physical properties, such as being colored, volatile, and exhibiting distinct odors.

What group is nickel in?
Nickel: Ni, atomic number 28, group 10, period 4.
Why is bromine in group 17?
Groups (or columns) on the periodic table put together elements that have similar qualities. Group 17 is called the halogens, and these elements have 7 valence electrons (electrons in their outer energy level) and therefore have similar characteristics.
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
Why can hydrogen be placed in either group 1 or 7 on the periodic table?
Hydrogen can be in both group 1 and group 7 due to it's valence shell. Hydrogen only needs 2 (or 0) electrons to be stable. Because it has 1 electron, it can either accept one (like a group 7 element) or give one away (like a group 1 element). It can act like either group.
Why is fluorine in group 7 of the periodic table?
Fluorine is in group 7 of the periodic table because it has 7 valence electrons. Group 7 elements, also known as the halogens, have a full outer shell of 7 electrons, making them highly reactive and likely to form compounds with other elements.
What're the similarities between group 1 and 7 in the periodic table?
All elements in Group 7 have the same number of electrons in their outermost shell and this number corresponds to the group number.
What are the differences and similarities between seven-tenths and seven-hundredths?
7/10 = 0.7 but 7/100 = 0.07
How would you compare and contrast the elements in group 1 and group 7 in the periodic table?
By listing their collective and individual properties, pointing out similarities and differences.
What is a mineral group?
A group of related minerals based on chemical similarities.
In geometry it is sometimes helpful to group objects and look at similarities between them?
True. In geometry it is sometimes helpful to group objects and look at similarities between them.
Similarities between group and team?
Some similarities between a group and a team are they are both comprised of 2 or more people. They often have similar goals or objectives in mind. Another similarities between a group and team is that they gather together for the same idea or purpose.
How many committees of 7 can be formed from a group of 10 people?

7 Tens equals how many ones?
Well, isn't that just a happy little math problem! If you have 7 tens, that's like having 7 groups of 10. And in each group of 10, there are 10 ones. So, if you have 7 tens, you have 70 ones. Just imagine all those little ones happily lining up to join the big group of tens!
