Answer:
a. have their particles arranged
Explanation:
<em>A crystalline solid is a solid material with a regular (crystal lattice) or irregular (amorphous) ordered array of its components,</em> being these molecules, atoms or ions. These arrengements are held in place thanks to the atraction between components, they can be ionic compounds held by their charges, metal cations surrounded by a sea of electrons, covalent networks with their atoms covalently bonded or molecular crystals held together by weak intermolecular forces.
I hope you find this information useful and interesting! Good luck!
D.
this is used for measuring atomic mass
AMU
<u>Answer:</u>
<u>For a:</u> The charge on the ion formed is +3
<u>For b:</u> The charge on the ion formed is -2
<u>For c:</u> The charge on the ion formed is +2
<u>Explanation:</u>
An ion is formed when an atom looses or gains electron.
- When an atom looses electrons, it will form a positive ion known as cation.
- When an atom gains electrons, it will form a negative ion known as anion.
For the given options:
Aluminium is the 13th element of the periodic table having electronic configuration of ![1s^22s^22p^63s^23p^1](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E23p%5E1)
This element will loose 3 electrons to form
ion
The charge on the ion formed is +3
Sulfur is the 16th element of the periodic table having electronic configuration of ![1s^22s^22p^63s^23p^4](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E23p%5E4)
This element will gain 2 electrons to form
ion
The charge on the ion formed is -2
Strontium is the 38th element of the periodic table having electronic configuration of ![1s^22s^22p^63s^23p^64s^23d^{10}4p^65s^2](https://tex.z-dn.net/?f=1s%5E22s%5E22p%5E63s%5E23p%5E64s%5E23d%5E%7B10%7D4p%5E65s%5E2)
This element will loose 2 electrons to form
ion
The charge on the ion formed is +2
An α particle is about 7300 times bigger than a ϐ particle
Beta radiation can damage a higher number of cells than alpha radiation.
The distinction between a chemical change and a physical change is best illustrated by the sentence. A physical change will alter the state of matter, but a chemical change results in the formation of a new substance. Therefore, choice A is right.
<u>How does chemistry change?</u>
Chemical reactions between various substances have changed, leading to the creation of new chemicals. The chemical properties of the substance are unaffected by physical changes. Chemical compounds wouldn't alter as a result of the physical change. The matter's physical state may change as a result of the physical change.
A physical change causes the formation of a new substance, whereas a chemical change alters the state of matter.
A physical change occurs naturally, but a chemical change is exploited by scientists to make new compounds. A physical change will result in a different state of matter, but a chemical change produces a new substance.
So the phrase that contrasts a chemical change with a physical change is the most accurate. A physical change will alter the state of matter, but a chemical change results in the formation of a new substance.
