Answer:
Below are some patterns in the charge for elements in each group.
Group 1 elements : 1 valence electron and form ions with charge +1
Group 2 elements : 2 valence electrons and form ions with charge + 2
Group 3 elements : 3 valence electrons and form ions with charge + 3(there are some exceptions as well)
Elements in groups 4 and 5 are unpredictable also the D block elements consist of multiple oxidation states..
Group 6 elements : 6 valence electrons, form ions with charge -2
Group 7 elements: 7 valence electrons, form ions with charge -1
The octet rule is being followed, the elements form either ionic bond or covalent bond to fulfill it.
eg: when a K atom forms a K+ ion, the ion has the same electron configuration as the noble gas Ar (argon).
When an O atom gains 2 electrons to form the O²⁻ ion, the ion has the same electron configuration as the noble gas Ne (neon).
Note: Boron (B) is in Group 3 but doesn't form ions.
There are two things that could be done. The first is to increase the mass of the objects. The second is to decrease the distance between the center of masses of the objects.
Answer:
I do not know if I am correct but I think it is the letter D I hope it helps you if it is correct pls brainliests
Answer:
A Beaker, however if you are doing this from home a measuring cup would probably be more available.
Hi,
Answer: 30,2220 Hours
<u>My work:</u> There are 60 minutes in every hour and 8,760 hours in a year. To,easily achieve this problem you take 8,760 the hours in a year and multiply it with 34.5. (8,760 * 34.5) By doing this you get your answer of 302,220 Hours, or in minutes it would be 18,133,200 minutes.
I Hoped I Helped!
