Could someone please explain isotopes, and what they do/are? If not thats fine, thank you
Answers
Answer:
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
"some elements have only one stable isotope"
Explanation:
there ya go! Pls give me brainliest!

Answer:
Newton meter,
Mass-spring system
Explanation:
Most commonly available Laboratory equipment is Newton meter.
It utilizes the spring system to subtend the hooked mass.
The dial indicates the amount of force required for the mass-spring system to be in equilibrium.
After performing the above described experiment. He should note down the atleast 5 sets readings given by the newton meter.
Average those 5 readings. The use the average answer to determine the mass as follows:
where g: is the gravitational constant 9.81 m /s^2

To solve the problem we must know about Melting, freezing, and boiling.
What is Melting?
Melting is the process by which a solid is converted to liquid.
What is Freezing?
Freezing is the process by which a liquid is converted to solid.
What is boiling?
Boiling is the vaporization of a liquid when it reaches its boiling temperature.
Now, as we know when there is a change in the phase of a substance, only the physical changes occur in that substance. For example, water when frozen, forms ice although there is a phase change the properties of the water are still the same, still, it will conduct electricity, etc.
Hence, Melting, freezing, and boiling are physical(phase) changes.
