Which group had elements on the periodic table that almost never react?
Noble gases or group 18 elements
How is the tendency to gain electrons changes as you go down the 16th group of periodic table?
actually it never changes as in 16 the group all the elements have 4 valence electrons in outermost shell so they can neither accept nor lose the electns
Are compounds created through physical changes?
No, only through chemical reactions. Physical changes never change the chemical makeup of something. For example, water tuning in to ice is a physical change. Ice and water both have the chemical symbol H20. On the other hand, a sodium - water reaction forms Sodium Hydroxide and Hydrogen. The compound, hydroxide, is formed.
How do to remember elements name down the group?
You really do not unless your daily work concerns the chemistry of different elements. It is never hard to find a periodic table of elements around a chemistry lab or office.
Is stim an element?
No, never heard of it and can't find it in the periodic table of (all!) elements
Which group had elements on the periodic table that almost never react?
Noble gases or group 18 elements
Why was group sixteen of the periodic table of elements never named?
It does have a name. Group 16 elements are called "chalcogens".
What is the mineral group of the mineral hafnium?
Hafnium is an element not a rock. Hafnium is never found in nature pure form so does not fit into any groups. Hafnium is a chemical element, a metal placed in the group 4 and period 6 of the periodic table of Mendeleev.
Where are the group 1 metals and what are they called on the periodic table?
They are named as Group(I) in the Periodic Table. However, they are also known as the Alkali Metals. They are Lithium, Sodium, Potassium, Rubidium, Caesium, and Francium. Francium is never found in the open lab, as it is radio-active.
Is it possible that an unknown group in the periodic table might be found?
This is to my opinion not very probable, though never say impossible: Today Mendelejev's Periodic Table looks rather incomplete, there were no 'transition' elements in it (group 3 - 12)
Which of the following groups in the periodic table contain elements so reactive that they are never found in the free state?
group 1 and 2
When is a chemical not a chemical?
never
How is the tendency to gain electrons changes as you go down the 16th group of periodic table?
actually it never changes as in 16 the group all the elements have 4 valence electrons in outermost shell so they can neither accept nor lose the electns
What makes group 18 on the periodic table special when bonding?
Group 18 is the Noble Gas Family. Since the outer energy level of all elements in the family are full they never bond except at extremely cold temperatures close to absolute zero.
Can your child support case close if you requested the forms but never signed them?
If you never signed and filed the forms then it is likely that a case was never opened.
