An ion is an atom or group of atoms in which the number of electron s is different from the number of proton s. If the number of electrons is less than the number of protons, the particle is a positive ion, also called a cation.
Are atoms physics or chemistry?
An atom is the basic building block of chemistry. It is the smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element.
What physics is used in chemistry?
Chemical physics is a subdiscipline of chemistry and physics that investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics; it is the branch of physics that studies chemical processes from the point of view of physics.
What is an ion GCSE physics?
An ion is an atom or group of atoms with a positive or negative charge .
What are electrons physics?
An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom — the other two are protons and neutrons. Together, electrons, protons and neutrons form an atom’s nucleus.
What is ions in biology?
Biology/Chemistry/Medicine definition: An ion is a charge-carrying atom or molecule with an unequal number of electrons and protons. It is formed by the process of ionization and plays several important roles in the biological world. Anions are negatively charged ions whereas cations are positively charged ions.
Whats harder chemistry or physics?
Physics is considered comparatively harder than chemistry and various other disciplines such as psychology, geology, biology, astronomy, computer science, and biochemistry. It is deemed difficult compared to other fields because the variety of abstract concepts and the level of maths in physics is incomparable.
Is high school physics harder than chemistry?
Physics is harder than chemistry, except at the high school level. Physics gets even more difficult once you start university. The math is more advanced and complex once you get to college. If you’re looking for a hard science major that provides you with more skills for a variety of jobs, then consider physics.
Should I study chemistry or physics first?
Chemistry is based upon physics, not the other way around, so of course you don’t have to study it first. You’re quite welcome. Don’t overlook the possibility of taking them both at the same time, but it might be a bit confusing because atoms tend to be thought of differently in the two fields.
Can physics exist without chemistry?
Without chemistry, physics cannot exist and without physics, chemistry cannot exist. The world in which we live follows fundamental laws that we can understand by physics and chemistry both.
Is chemistry basically physics?
Chemistry is a highly developed specific part of physics that studies ordinary matter, particularly molecules (as in gases), solutions (liquids) and materials (solids) and their transformations. Fundamentally it is all based on the physics of electrons and the electromagnetic field.
Is chemistry similar to physics?
Physics and chemistry are similar in a few ways. They both study matter, though chemistry studies what makes up matter, and physics studies how matter interacts. They are both physical sciences and areas within these two fields of science overlap at times.
What is an ion GCSE chemistry?
Ions are electrically charged particles formed when atoms lose or gain electrons . This loss or gain leaves a full outer shell, so the electronic structure of an ion is the same as that of a noble gas (such as helium, neon or argon).
What are atoms GCSE chemistry?
Atoms are very small particles made up of a electrons orbiting a nucleus. The nucleus is made out of protons and neutrons. Protons, Neutrons and Electrons are called subatomic particles. ‘Subatomic’ means ‘inside the atom’.
What are ions BBC Bitesize?
An ion is an atom or group of atoms with a positive or negative charge .
What is photon physics?
Photons are fundamental subatomic particles that carry the electromagnetic force — or, in simpler terms, they are light particles (and so much more). The photon is also the “quantum,” or fundamental unit, of electromagnetic radiation.
What is a proton in physics?
proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
What is neutron physics?
neutron, neutral subatomic particle that is a constituent of every atomic nucleus except ordinary hydrogen. It has no electric charge and a rest mass equal to 1.67492749804 × 10−27 kg—marginally greater than that of the proton but 1,838.68 times greater than that of the electron.
Does the human body have ions?
Many normal substances exist in the body as ions. Common examples include sodium, potassium, calcium, chloride, and bicarbonate. These substances are known as electrolytes.
Why ions is important in human?
Functions of the main electrolytes (ions) Regulate osmotic pressure and the body’s water content, transmit nerve signals, contract muscles, etc. Transmit nerve signals, and contract muscles including the heart, etc. Contract muscles, form bones and teeth, activate enzymes, etc.
What is ion in slang?
This ion means “I don’t.” It is a spelling based on the colloquial pronunciation of I don’t, especially in Black English.
What is the hardest science?
Physics. Generally, physics is often deemed to be the hardest of all the sciences, especially as an A level qualification. Physics involves a lot of complex maths content – an aspect that most students struggle with.
Is physics or biology easier?
Beginning university students in the sciences usually consider biology to be much easier than physics or chemistry. From their experience in high school, physics has math and formulae that must be understood to be applied correctly, but the study of biology relies mainly on memorization.
Is physics harder than calculus?
Physics is absolutely harder than calculus. Calculus is an intermediate level of mathematics that is usually taught during the first two years of most STEM majors. Physics on the other hand is a very advanced and difficult and highly researched field.
What is the toughest subject in the world?

- Chartered Accountancy.
- Medicine.
- Pharmacy.
- Architecture.
- Law.
- Psychology.
- Aeronautics.
