Phorgum is an arrangment similar to the periodic table. We may arrange elements or compounds based on its properties. Arrangement can be made on the basis of rows, columns, ascending and descending order.
Answer:
Two elements in same group having similar properties.
Explanation:
The elements shows similar properties if they have same number of valance electrons.
As we move left to right in periodic table the number of valance electrons increases in case of every element
When we move top to down in the group of periodic table the number of valance electrons remain same. So the elements in same group shows similar properties.
For example:
Fluorine and chlorine are present in same group, both have same valance electrons so they shows similar properties.
Electronic configuration of fluorine.
F₉ = [He] 2s² 2p⁵
Electronic configuration of chlorine.
Cl₁₇ = [Ne] 3s² 3p⁵
Both have same number of valance electrons that's why showing similar physical and chemical properties.
As the O3 suggests, the Ozone molecule is made up of 3 Oxygen atoms.
Answer:
science is nothing without funding
Explanation:
Well Science in the US is highly a political affair. Scientists need funding for research, so they usually have to obtain grants from people who have the means to spare it. In many cases that means people who are involved with the government, or have close ties to it.
So scientists find themselves having to play off partisan politics in order to secure the funding they need for their research. Many times they also find that their research will inevitably get skewn to meet the original funders own ends.
Mostly what I have said is commonly known. However I am in school, and deal with scientists and doctoral researchers who have expressed and validated similar experiences.
