Please someone help my on my question
An element can be represented symbolically in terms of its atomic number and mass number as:
\[_{Z}^{A}\textrm{X}\]
where X = symbol of the element
A = atomic mass
Z = atomic number
In this case we have the representation as:
\[_{0}^{1}\textrm{n}\]
where n = symbol for neutron
mass number of neutron = 1
charge/atomic number of neutron = 0
Ans: D) A neutron of zero charge and one unit mass
Answer:
The Answer is B: subtract atomic mass from atomic number. I remember doing this in 8th grade!!!:)
Explanation:
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom and the atomic number.
Talc is not a good choice when building a statue because the mineral Talc is one of the weakest minerals on the Mohs Scale with a hardness of 1 since it could be scratched by a fingernail, which means that when people build a statue with Talc, it could be easily broken down.
