By measuring the temperature of a thing it can be determined whether it is hot or cold. Temperature of the thing can be measured by degree Centigrade or by degree Fahrenheit. This is the instrument that will exactly measure the temperature of the substance and whether it is hot or cold. If the substance has a higher temperature than our body temperature then it would automatically feel hot to us and if the temperature of the substance is lower than our body temperature, then it will definitely feel cold to us. This is our sense telling us whether the substance in question is hot or cold.
It’s [Xe]7s^2 5f^14 (first one) hopefully i could help!!
Answer:
X has 9 Electrons, 9 Protons and 10 Neutrons
X is Fluorine
Explanation:
19 in X is Nucleon number
So, if you minus 19 by 9 down there (which is proton number) you'll get 10 (Neutron number).
Now, Proton = Electron. That's why Electron is 9 too. I figured that X is Fluorine bcuz it has 9 Electrons. If you venture around in the periodic table, fluorine is the ninth element innit.
hope this helps ya ＼(^o^)／
Answer:
Explanation:
