Why the metal elements are hard?
have very high density and have high atomic mass
When two nuclei of light elements are forced together at extremely high temperature what happens?
They form heavier elements
Is osmosis a type of transport involving elements such as calcium?
Osmosis is a type of passive transport that involves elements such as calcium. The elements are moved from high concentration to low concentration.
What are the elecronegativity trends seen in the periodic table?
On the Periodic Table of elements, electronegativity increases as you move left to right across a period.
What is the family of nonmetal elements with high reactivity?
I believe it's halogens
What is the elements in order from the highest elecronegativity?
Fluorine has the highest electronegativity.
What is the elecronegativity of chlorine?
3.16
Why the metal elements are hard?
have very high density and have high atomic mass
Why do transition elements have high polarising power?
TRANSITION ELEMENTS HAVE d-ORBITAL IN THEIR SHELL WHICH HAS LOW SHIELDING EFFECT. DUE TO WHICH THEY HAVE HIGH EFFECTIVE NUCLEAR CHARGE. SO, HIGH POLARIZING POWER.
What is high temperature fusion?
when nuclei of different elements are forced together to create different elements
How many elements do you learn in Middle school?
I believe that its 16 elements, but that changes in high school.
Why do elements for bonds?
Elements for bonds because they have a high tendency to be stable, this means that they have high tendency to attain the octet or doublet rule (only in the case of hydrogen).
What element is used in high speed drills and abrsives?
There are a couple of elements that are mainly used in high-speed drills and abrasives. These elements are tungsten and diamond, or carbon.
Elements which have high electronegativities occur in Group?
VIIA
Under what conditions are ionic bonds formed?
Must involve two different elements. Can not be formed with same affinity elements. Low affinity elements with high affinity elements.
Why do chemists use compounds instead of group 1 and 7 elements?
It is because the group 1 and 7 elements have a high reactivity. The reactivity is far too high to use on there own because the elements in these groups react with air and/or water.
When two nuclei of light elements are forced together at extremely high temperature what happens?
They form heavier elements
