How many chromosomes are there in each human body cell?
There are 46 chromosomes in each human body cell, with 23 chromosomes inherited from each parent. This includes 22 pairs of autosomes and 1 pair of sex chromosomes (XX for females, XY for males).
What milestone represent 60th birthday?
The milestone that represents a 60th birthday is often referred to as the "diamond jubilee." It is a significant celebration, symbolizing many years of life and experience. Many people mark this occasion with special parties and gatherings to honor the person reaching this milestone.
What is te future of cell phones?
If you're using a cell phone for so many years, you would really see the vast improvement of the gadget. Every year the face and all the applications of cell phones will be change. Designers of cell phones around the world are busy designing units that will drop calls- but look exceptionally doing it. We have to expect something different, something fresh and more high- tech than our old mobile phones.
What is reaction that can be reduced due to lung damage?
Many things can be slowed down and otherwise adversely affected by lung damage. The lungs' most important function, breathing, is certainly one of these things that is affected when the lungs are damaged.
What are free radicals?
Free radicals, also known simply as radicals, are organic molecules responsible for aging, tissue damage, and possibly some diseases. These molecules are very unstable, therefore they look to bond with other molecules, destroying their health and further continuing the damaging process. Antioxidants, present in many foods, are molecules that prevent free radicals from harming healthy tissue. Your body comprises trillions of cells. Cells, in turn, are made up of many molecules. Molecules consist of atoms joined by chemical bonds. Atoms consist of neutrons, protons, and electrons. The number of positively charged protons in the atom's nucleus determines the number of negatively charged electrons surrounding the atom. Electrons orbit an atom in one or more shells. When the innermost shell has two electrons, it is full; when the second shell has eight electrons, it is full, and so on. Chemical reactions involve the transfer of electrons, which bond atoms together to form molecules. The number of electrons in an atom's outer shell is an important way to determine its chemical behavior. A substance that has a full outer shell tends to be inert and tends not to react chemically. Atoms reach this state of stability by gaining electrons to fill their outer shells, or by bonding together with other atoms and sharing electrons in order to complete their outer shells. When molecules split, they normally don't leave molecules with unpaired electrons. But when weak bonds split, they leave one or more molecules with unpaired electrons, called free radicals. Free radicals are positively charged, very unstable, and react quickly with other molecules, to acquire the electron they need to gain stability. Generally, free radicals acquire an electron from the nearest stable molecule. The molecule that loses an electron then becomes a free radical itself, beginning a chain reaction. Once the process is started, it can cascade. Excessive free radicals in your cells can attack the cell membranes, causing cell and tissue damage. Free radicals can also break strands of DNA (the genetic material in your cells), which can lead to cancer.
How many carbon atoms are there in a diamond?
There is no such thing as a "diamond molecule"; a diamond is just crystalized carbon atoms. In another sense, a diamond is one big, visible molecule. A one-carat diamond is one big molecule weighing 0.2g and having 10 sextillion atoms. Lots and lots of atoms!
How many atoms are in a diamond?
A diamond is composed of carbon atoms. The crystal structure of a diamond contains carbon atoms bonded together in a repeating pattern, with each carbon atom forming four covalent bonds with surrounding carbon atoms. This means that a diamond contains a very large number of carbon atoms, typically on the order of 10^23 atoms.
How many diamond cubic atoms are present in a single unit cell?
There are 8 diamond cubic atoms present in a single unit cell.
Is diamond 100 percent carbon?
yes, diamond is made of carbon. Diamond is a macromolecule made of many carbon atoms. Each carbon atom is joined to 4 more carbon atoms each. Having each atom of carbon bonded to four other atoms is why diamond is so hard- there are lots of strong chemical bonds to overcome.
How many protons and neutrons does a diamond have?
A diamond is composed of carbon atoms. The atomic number of carbon is 6, so all carbon atoms have 6 protons in their nuclei. The number of neutrons depends on the isotope of carbon. Carbon-11 atoms have 5 neutrons, carbon-12 atoms have 6 neutrons, carbon-13 atoms have 7 neutrons, and carbon-14 atoms have 8 neutrons. Refer to the related links below to see the Wikipedia articles on carbon and diamond.
How many atoms are in diamond?
Millions/billions. However, they are all CARBON atoms. This is because diamond is an ALLOTROPE of Carbon. Any one carbon atom will be combined in a single bonds to four adjacent carbon atoms. Allotropes are when a given element displays itself in a certain manner. Other allotropes of carbon are Graphite , and Buckminster Fullerene (Footballene).
How many carbon atoms are in the graphite unit cell?
there are many different atoms some are called sex cells bloood cells white blood cells and many more cells...yeah this is a cell's answer not an atom answer muhahahahahha biach you got wasted!
How many carbon atoms are in 2 grams of 1 carat diamond?
There are about 1.092 x 10^21 carbon atoms in 2 grams of 1 carat diamond. This is calculated based on the molar mass of carbon and Avogadro's number.
What is the atomic number of diamond?
Diamond does not technically have an atomic number as it is not an element. a diamond is a crystal made from many atoms of carbon which has an atomic number of 6.
How many carbon atoms in a hope diamond of 44.4 carrots?
A carrot? Well I'll assume you mean carat. A carat is unit of mass used by the diamond trade. 1 carat is 200mg. 44.4 carats is therefore 8.8 grams Diamonds are pure carbon. Avogadros number tells us ho many atoms are in a gram atom of carbon this is 6.023x1023 atoms in 12.011 grams of carbon therefore there are (6.023/12.011) X 8.8 X 1023 atoms I make that 4.41 x 1023 atoms
What is hardest object diamond or platinum?
Diamond, Its atom structure formed by many carbon atoms in such a way makes it very strong indeed
How many covalent bonds are in a diamond lattice?
In a diamond lattice, each carbon atom forms four covalent bonds with its neighboring carbon atoms. Therefore, there are four covalent bonds in a diamond lattice structure.
