Not sure how in depth or what level of particles but I will go as deep as I know. The matter that makes up the world is comprised of 12 particles which are known as fermions. There are 12 fermions which are made up of 6 quarks (up, charm, top, Down, Strange, Bottom) 3 electrons (electron, muon, tau) and three neutrinos (e, muon, tau). Technically, only the up quark, down quark, electron, and electron neutrino are necessary to create all known matter since others would simply be very unstable and decay into those particles. The other type of particles are known as Bosons. These particles transmit forces and all sorts of different interactions. I have included a photo from online which describes the main characteristics of each elementary particle.
<span>The
density of an object is defined to be its mass divided by the volume it
occupies. For this problem, the mass of the cube was given to be 25 g while its
volume is 125 cm</span>³. Thus, we simply divide 25 g by 125 cm³ to get the object’s density. We then calculate that the cube has a density of
0.2 g/ cm³.
Answers:
2. valence electrons
3. a bond formed when atoms share one or more pairs of electrons.
4. chemical formula
5. a. calcium - 2
b. carbon - 4
c. sulfur - 6
6. a. electrons
7. the elements that make up water can't be split into a simpler form, but water can. water is a liquid at room temperature, oxygen and hydrogen are gases at room temperature.
8. because it is made of oxygen and hydrogen and one is partially negative and one is partially positive.
explanation: you’re welcome.
A single bond contains <u>two</u> shared electrons.
Answer:
- COVELENT BOND:-The chemical bond formed by the sharing of an electron pair between two atoms so that both the atoms get their octet complete is called covalent bond
- SINGLE COVELENT BOND:-it is formed by sharing of one pair of electron between two atoms
- DOUBLE COVELENT BOND:-it is formed by sharing of two pair of electron between two atoms
- TRIPLE COVELENT BOND:- it us formed by sharing of three pair of electron beyween two atoms
2)Electron dot structures of carbon dioxide:-Oxygen atom contains 6 valence electrons which form 2 lone pairs. Since it is bonded to only one carbon atom, it must form a double bond. Carbon atom contains four valence electrons, resulting in zero lone pairs. Therefore, it is doubly bonded to each oxygen atom.
3))Sulfur has an atomic number is 16 with the
symbol as 'S'
- The electronic configuration of sulfur is said to be 2,8,6
- The valence electrons present in sulfur is 6.
- Sulfur forms an octet structure by connecting 8 sulfur atoms with each other by the formation of single covalent bonds.
- The sulfur molecule's chemical formula is S8.
- Sulfur is usually used in the manufacture of sulphuric acid.
