Which two subatomic particles are present in equal numbers in an atom?

User Avatar

Asked by Wiki User

In each neutral atom of any given element, the numbers of electrons and protons are equal, as the charges in the atom must balance. Only the neutron number may vary amongst atoms of the same element.

For most substances the distance between particles is smallest when the substance?

User Avatar

Asked by Wiki User

For most substances, the distance between particles is smallest when the substance is in its solid state. In a solid, particles are densely packed and held closely together by strong intermolecular forces, resulting in a smaller distance between particles compared to liquids or gases where particles are more spaced out.

Number and type of element of the atom fe2o3?

User Avatar

Asked by Wiki User

Four: the answer to such questions is always obtainable by summing the subscripts in the formula (remembering that no explicit subscript means one atom per formula unit of the element symbol without a subscript) unless the formula includes parentheses; in that instance, the subscripts within the parentheses must be multiplied by the subscript after the right parenthesis before summing.

What subatomic particle plays the most important role in chemistry?

User Avatar

Asked by Wiki User

Electrons are the subatomic particles that play the most important role in chemistry. They determine how atoms interact with each other to form molecules through their configuration in energy levels and the sharing or transfer of electrons between atoms.

What is the structure of SO3 according to vesper theory?

User Avatar

Asked by Wiki User

According to VSEPR (valence shell electron pair repulsion) theory, the molecular structure of SO3 is trigonal planar. This means that the sulfur atom is surrounded by three oxygen atoms arranged in a flat, triangular shape, with bond angles of approximately 120 degrees.

What is the process in which the nuclei of two atoms combine to form a larger nucleus?

User Avatar

Asked by Wiki User

The process in which the nuclei of two atoms combine to form a larger nucleus is called nuclear fusion. This process releases a large amount of energy, such as in the sun where hydrogen atoms fuse to form helium. Fusion is the opposite of nuclear fission, which is the splitting of a larger nucleus into two smaller nuclei.

Whow do isotopes differ from each other?

User Avatar

Asked by Wiki User

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This difference in the number of neutrons gives isotopes different atomic weights, but they still have the same chemical properties.

If an atom is made up of 6 protons 7 neutrons and 6 electrons then what is it's atomic number?

User Avatar

Asked by Wiki User

All you need to determine the atomic number is the amount of protons, because it is these sub-atomic particles which enable us to identify an atom. All atoms of the same element have a unique number of protons. In this case, the atomic number is six.

How are the number of electron shells determined?

User Avatar

Asked by Wiki User

The number of electron shells in an atom is determined by the principal quantum number (n). This number indicates the energy level of the shell, with larger values of n corresponding to higher energy levels. Each shell can hold a maximum number of electrons based on the formula 2n^2.

What property gives carbon atom compatibility?

User Avatar

Asked by Wiki User

The property that gives carbon atom compatibility is its ability to form four strong covalent bonds with other atoms. This allows carbon to form a wide variety of stable organic compounds, making it the building block for life as we know it.

The number of electrons shared among the carbon atoms in a benzene ring is?

User Avatar

Asked by Wiki User

In a benzene ring, each carbon atom shares one electron with each of its neighboring carbon atoms in a delocalized pi system, contributed by a total of six carbon atoms. This shared electron cloud forms a stable aromatic ring system with alternating single and double bonds.

How many neutrons does a cesium 141 have?

User Avatar

Asked by Wiki User

The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.

Who made the statement that a neutral atom has the same number of protons and electrons?

User Avatar

Asked by Wiki User

The statement that a neutral atom has the same number of protons and electrons is a fundamental concept in chemistry that can be attributed to many scientists throughout history. It is a basic principle known as the electrical neutrality of an atom, where the positive charge of the protons is balanced by the negative charge of the electrons, creating a neutral overall charge for the atom.

What is the nuclear symbol and the hyphen notation for a carbon isotope with a mass number of 14 and atomic number of 6?

User Avatar

Asked by Wiki User

Note that since all carbon isotopes have an atomic number of 6, it is not necessary to state the atomic number; the fact that it is carbon means that it has the atomic number 6. So the isotope with a mass number of 14 is called carbon 14. As a symbol, it is C with a superscript 14 (which I am not able to type).

What are some examples of hydrocarbons containing 5 carbon atoms?

User Avatar

Asked by Wiki User

Some examples of hydrocarbons containing 5 carbon atoms include pentane, cyclopentane, and 1,1-dimethylbutane. These hydrocarbons belong to the alkane family and have different structures and properties based on their arrangement of carbon and hydrogen atoms.

Suppose the electron and proton charges differed by one part in one billion?

User Avatar

Asked by Wiki User

If the electron and proton charges differed by one part in one billion, atoms wouldn't be stable because the electromagnetic force plays a crucial role in holding them together. This imbalance would likely result in unstable nuclei and chemical reactions, making life as we know it impossible.

Carbohydrates are biochemicals that are composed of one or more?

User Avatar

Asked by Wiki User

Carbohydrates are biochemicals composed of carbon, hydrogen, and oxygen atoms. They are the main source of energy for the body and are classified as simple (sugars) or complex (starches and fibers) based on their chemical structure.

How many neutrons are in colbalt 60?

User Avatar

Asked by Wiki User

Cobalt (Co) has the common form of cobalt 60, ie its atomic mass is 60. Its atomic number is 27. Atomic mass is made up of protons and neutrons. Atomic number is number of protons. Hence number of neutrons is 60 - 27 = 33/

Do egg white polar or non-polar?

User Avatar

Asked by Wiki User

Egg white is mainly composed of water and proteins such as albumin. Water is a polar molecule, while proteins contain polar and non-polar regions. Overall, egg white can be considered polar due to the presence of water and polar regions in the proteins.

Sulfur contains how many valence electrons?

User Avatar

Asked by Wiki User

Group 16 (VIB or VIA) elements have six valence electrons.

What is the ion charge for 16 protons 18 electrons?

User Avatar

Asked by Wiki User

The ion charge for an atom with 16 protons and 18 electrons would be a 2- charge. This is because there are 16 positive charges from the protons and 18 negative charges from the electrons, resulting in a net charge of -2.

What is an object in which the electrons at one end spin in one direction and the electrons at the other end spin in an opposite direction?

User Avatar

Asked by Wiki User

This is referring to a magnetic object with domains, such as a magnet. In a magnet, the electrons align in such a way that their spins are opposite at each end, creating a magnetic field.

Particles of an atom that lack any changes are called?

User Avatar

Asked by Wiki User

Neutrons.

The particles of an atom are: -

protons ; charge (+) relative mass is '1'

neutrons ; charge (0) relative mass is '1'

electrons ; charge (-) relative mass is '1/1860'.

For any given element the numbers of protons , neutrons and electrons will vary.

Does sn gain or lose electrons?

User Avatar

Asked by Wiki User

Sulfur typically gains electrons to form a stable electron configuration. It can gain up to two electrons to achieve a full valence shell of eight electrons.

Which element has 27 protons and 27 electrons per atom?

User Avatar

Asked by Wiki User

cobalt

you can use the periodic table to find answers to questions like this. its super easy- protons are the same as the atomic number, so whatever the atomic number is of the element on the periodic table, that's how many protons the atom has.
