Answer:
think it's C but my gut is telling me A
Explanation:
Answer:
a. True
Explanation:
In the periodic table , all the elements are placed in a certain fashion , i.e. , with increasing atomic number.
Since ,
The element lithium and nitrogen are placed , in group 1 and 15 respectively.
as we go from left to right , across the group , the atomic radius decreases ,
Because ,
As , we go left to right , the number of electrons increases in the same shell , and proton too increases , which in turn increases the nuclear attraction , and the nucleus holds on to the electrons more firmly , and hence , the size reduces , as the electrons increases , in the same shell.
Hence, the given statement is true.
The accepted model of an atom was made by Schrodinger, which is known as the quantum mechanical model. Unlike Bohr's model, electrons are represented as a cloud and not small balls orbiting the nucleus. There is no define path of electrons in Schrodinger's model, but it can predict the odds of where an electron is located.
The answer to your question is then Electrons form a cloud around the nucleus.
Answer:
B it has increased slightly
