In this case charge may be calculated by its combination with other ions, for example an element 'M' combines with two chloride ions, MCl2 then its charge must be +2.

Are the number of protons always equal to the number of neutrons?

No, in fact, they rarely are equal. There are different forms of the same type of atom. For example, there are three isotopes of Hydrogen, an element that has one proton. Hydrogen-1 has no neutrons. Hydrogen-2 has one neutron. Hydrogen-3 has two neutrons.


How can you find the nucleus with no mass number?

you cant get the # of neutrons if there is no atomic mass because you have to subtract the atomic # from the atomic mass #. so there is no way that u can find the # of neutrons without the atomic mass it is needed!


What has the mass number of 41?

The mass number of an element is the total number of protons and neutrons in its nucleus. Given that the atomic number (number of protons) uniquely identifies an element, knowing just the mass number of 41 is insufficient to determine the specific element without additional information.


How is the mass number different from the atomic number of an atom?

Atomic number of an element is the number of protons that an atom of an element contains. The atomic weight (the mass of the atom) is measured by not only the mass of the proton(s), but by the mass of the nuetrons and electrons too.


What is a stream of particles containing two neutrons and two protons?

A stream of particles containing two neutrons and two protons is an alpha particle. Alpha particles are emitted during alpha decay in radioactive processes. They have a positive charge and are relatively heavy compared to other types of particles.

What subatomic particles could be changed without changing which element the atom?

You are probably referring to neutrons which are often found within the nucleus of an atom in numbers different from the protons. An atom of the element carbon, for instance, normally consists of 12 protons, 12 electrons and 12 neutrons. However, an isotope of carbon known as C13 consists of 12 protons, 12 electrons and 13 neutrons.


Why doesnt the number of protons change for a single element while the neutrons and electrons can?

The number of protons in an atom determines its identity as a specific element. Changing the number of protons would change the element. Neutrons and electrons can be added or removed without changing the identity of the element since they do not affect the element's chemical properties.


Can you identify an atom without knowing number of neutrons in it?

Yes, and in order to find the Number of Neutrons, subtract Atomic Mass from Number Of Protons, the result will be the Number of Neutrons for that atom *No. Of Neutron=Atomic Mass - Number Of Protons

How many protons neutrons and electrons does Fe-56 have?

It doesn't matter if it's 56Fe or 49Fe; the number of protons in an atom of iron will remain constant. Why? Because if there was one more electron, it wouldn't be Fe anymore: it'd be cobalt (Co). The number of protons determines the element, the only thing that can change regarding the nuclear makeup of an atom without changing the element is the number of electrons. The 56 stands for the atomic weight of that particular isotope of iron. If each neutron and each proton weigh 1 amu each, then the atomic weight minus the number of protons will give you the number of neutrons.


What subatomic particles could be changed without changing which element the atom is?

The element that an atom is is determined by the number of protons. The number of electrons can be changed (creating an ion), and the number of neutrons can be changed (creating an isotope), and as long as the number of protons does not change, the element that the atom is does not change.


What are the three fundamental particles that make up atoms?

Atoms are the basic constituents of matter. Protons, Neutrons, And Electrons are the main partilces. Electrons orbit outside nucleus. Protons and neutrons reside in the nucleus.


Did Mendeleev know about protons neutrons and electrons?

No, Mendeleev did not know about protons, neutrons, and electrons. He is best known for creating the periodic table of elements based on the properties of the elements without knowledge of the atomic structure. The discovery of protons, neutrons, and electrons came later with the development of atomic theory.


How would you calculate the atomic mass of atom without using the periodic table if you know the number of protons electrons and neutrons?

Add the number of protons plus the number of neutrons for an approximate answer. Compared to protons and neutrons, electrons have zero mass - it takes over 1800 electrons to equal the mass of a proton or neutron.


How do you find out the mass number of an element without knowing the protons and neutrons?

It is not possible.


Which subatomic particles contribute the most to the mass of potassium?

The protons and neutrons contribute the most to the mass of potassium. Protons have a positive charge and determine the element's identity, while neutrons provide additional mass without affecting the charge. Electrons have negligible mass compared to protons and neutrons.


The smallest particles into which an element may be broken down without changing the identity of the elements are?

Atoms are the smallest particles into which an element can be broken down without changing its identity. Each atom is made of protons, neutrons, and electrons specific to that element.
