<h2>Answer:</h2>
<u>The number of neutrons is </u><u>47</u>
<h2>Explanation:</h2>
In order to find the number of neutrons we subtract the atomic number from the atomic mass.
In the given case the atomic number is 23 and mass number is 70 so
No of neutrons is 70 -23 = 47
Hey there!
Okay so, the Lithosphere is made out of Earth’s outermost layer, which is composed of rocks in the crust and the upper mantle that behave as brittle solids.
The Mantle is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals.
The Core has two parts. The solid inner core made up of iron. The outer core is surrounded by a liquid composed of a nickel-iron alloy.
I hope this helps!
Answer:
maybe phone cause matter is a solid liquid or gad
Ionic compounds typically have high melting and boiling points, and are hard and brittle. when melted or dissolved they become highly conductive, because the ions are mobilized.
Answer:
a) the charge of an electron is equivalent to the magnitude of the elementary charge but barring a negative sign since the side of the elementary charge is roughly 1.602 * 10 - 19 Columbus then the charge of the electronic is-1.602 * 10 - 19
b) b=2T on the electron moving in the magnetic field
