<span>Because of the octet rule, it is easy to predict the charge of the ion of an element. Look at the number of valence electrons the element has. If it is between 1 and 4 the atom will most likely loose those electrons to become stable, making it a positive ion with the charge of the number of electrons it will lose. If it has between 4 and 8 valence electrons the atom will most likely gain electrons to achieve a full outer ring of 8 electrons. Its atom will have a negative charge of the number of electrons it needs to have 8 total. Hope I Helped If You Don't Mind May I Have A Brainliest Answer Please? :)</span>
Answer: Protons
WHY?
Changing electrons will only result in the same element having different charges and hence, changing it's chemical properties.
Changing neutrons will not change an element but it will result in an isotope forming instead. (Isotopes are elements of the same type with different neutron numbers.)
However, changing the proton number would immediately change the nucleus composition, resulting in a change in element with a negative charge as there are more electrons than protons. This results in a expansion in valance electrons's distance from the nucleus. This results in a change in chemical properties of the element.
Therefore, a change in Protons is the answer.
Answer:
Halogen Family of elements
Explanation:
Group Seventeen
Assuming the volume of the gas is measured at standard temperature and pressure, Then one mole of the Gas would occupy 22.4 liters.
Therefore, 1 liter is 1/224 moles
one mole of nitrogen 14 is 14
Therefore 1 liter of the nitrogen weighs 1/224×14
0.0625 grams
A = mass number which is equal to the total number of protons + number of neutrons, Z= atomic number of any element which is also indicates Number of protons or number of electron in the given atom.
The formula to calculate neutron would be :
mass number - proton
31 - 15 = 16
Thus 16 neutrons are found in one atom of P
There are 4 atom in one molecule
Thus
4 atom /1 molecule * 9 molecule * 16 neutron / 1 atom
= 4*9*16= 576 neutrons
