Explanation:
calcium ion is denoted as - Ca ²⁺
The number of electrons in a neutral atom of calcium = 20 , but since ,
it is charged atom ,
i.e. +2 , the number of electrons in calcium ion = 18 .
From , the question ,
The mass number = 41 ,
and
since ,
the mass number = number of protons + number of neutrons .
number of neutrons = mass number - number of protons
since ,
The number of protons for calcium ion = 20
number of neutrons = 41 - 20 = 21
Hence ,
number of neutrons = 21.
An empirical formula is the chemical formula showing the simplest ratio of elements in a compound rather than the total number of atoms.
For example the molecule 'CH2O' is the empirical formula for glucose.
Cerebrum is the part of the brain that we use for imagination, thinking, judgement etc. It is also the largest part of the brain
Cerebellum is in charge of stuff like the spinal cord
and the brain stem is the part of the brain that helps us move. (if you watch the walking dead in one of the episodes it teaches this xD)
hope this helped (:
