How many atoms make up a head of a pin?

depends on the sharpness of the aformentioned pin :)


How many atoms on a head of a pin?

There are approximately 1.2 x 10^20 atoms on the head of a pin. This estimate is calculated based on the size of a typical pinhead (about 0.5 mm in diameter) and the average spacing between atoms in a solid material.


If an atom is 10 to the power of -10 in diameter how many can you fit in a straight line across a pin head 0.1mm wide?

10^-10 basically means that an atom is 10 billionth of a metre. This means that 10 billion atoms can fit across in a line in 1 metre. A millimetre is a 1000th of a metre so 10 billion divided by 1000 equals 10 million. 10 million atoms fit in a straight line along a millimetre. However, you want 0.1mm. To get 0.1mm you have you divide 1mm by 10. You do the same to the atom number so 10 million divided by 10 equals 1 million. Answer: 1 million atoms


Explain why the atoms neutron nucleus atom molecule and the head of a pin is smallest to largest?

The order from smallest to largest is: atom, neutron, nucleus, molecule, head of a pin. Atoms are the smallest unit of matter, composed of a nucleus (protons and neutrons) surrounded by electrons. Neutrons are subatomic particles found within the nucleus of an atom. Nucleus is the central part of an atom containing protons and neutrons. Molecules are formed when atoms chemically bond together. The head of a pin is significantly larger compared to molecules.


What is a dressmaker pin mostly used for?

It is frequently asked, "How many angels can dance on the head of a pin?" The "pin" that is referred to is a dressmaker pin. This common pin is usually about 1 inch long with a round or flat head about 1/8 inch in diameter. It is used for pinning two or more pieces of fabric together before the fabric is sewn together with a needle and thread. Of course, the pins can be used to pin together paper, leather (if the leather is thin enough to push a pin through it), etc.
