Answer:
The mass number of an isotope is the sum of neutrons and protons.
Explanation:
In any elemental isotope, the only things that will affect molar mass and mass number is the number of protons and neutrons. Electrons are not counted because we usually assume they are equal to the amount of protons and have no weight.
Protons are what gives the element its atomic number and the neutrons determine the type of isotope it is within the element.
For instance:
There can be a regular Carbon - 12
But there are isotopes like Carbon - 13 and Carbon - 14.
*The number of protons stays the same but the number of neutrons are different
Answer Water, wind, and ice can also move pieces of rock or land to new places. The wearing away of a surface of rock or soil is called weathering. ... Weathering and erosion can cause changes to the shape, size, and texture of different landforms (such as mountains, riverbeds, beaches, etc).:

Answer:
Both metals and non metals.
Explanation:
The correct formula of baking soda is NaHCO₃,
An element is considered to be metal if it is able to give electron easily due to very low ionization energy.
A non metal is ready to accept electron easily due to high electron affinity.
In sodium bicarbonate :
Na: Sodium : metal
H : Hydrogen: non metal (although placed with first group, alkali metals, in the periodic table as it readily loses electron like metals)
C: Carbon: Non metal
O : Oxygen : Non metal.
So the compound contains both metals and non metals.
