Because energy is needed to alive so when glucose goes into oxygen cells it provides energy in the form of Atp
Answer: B
Reason: because the temp drops fast
Maybe isotopes but if you need a name isotopes of carbon because their number of electrons remains unchanged
<u>Answer:</u> The correct answer is d-block.
<u>Explanation:</u>
Chromium is the 24th element of the periodic table. It belongs to period 4 and Group 6 of the periodic table.
The number of electrons present in this element are 24 because number of electrons is equal to the atomic number of the element.
Electronic configuration of this element is: ![[Ar]4s^23d^4](https://tex.z-dn.net/?f=%5BAr%5D4s%5E23d%5E4)
As, the last electron is entering the d-orbital. Hence, this element belongs to d-block of the periodic table.
Answer:
10 neutrons
Explanation:
The mass of is made up of the total protons and neutrons in an atom.
Each particle has a mass of 1 amu (atomic mass unit).
All fluorine atoms have 9 protons.
If each proton is 1 amu, the protons must contribute 9 amu to the total mass of the atom (9 x 1 amu = 9 amu).
This means the neutrons must contribute a total mass of 10 amu (18.998 amu - 9 amu = ~10 amu).
If each neutron has a mass of 1 amu, there must be 10 neutrons in a fluorine atom (10 amu / 1 amu = 10 amu).
