What else can I help you with?
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 do you find the mass number of an element or compound without knowing the number of neutrons?
Atomic weight is really the only way to know how many neutrons there are. However, if you have no reason to think that you are dealing with an unusual isotope, you can assume the normal distribution of isotopes.
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.
Can you identify an atom without number of neutrons in it?
Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.
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.
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.
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.
Which of these can vary without changing the identity of an element number?
The mass number can vary without changing the identity of an element, as it represents the number of protons and neutrons in the nucleus. Conversely, changing the number of protons would change the identity of the element, as it defines the element's atomic number.
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.
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.
What element has A neutrons in its nucleus?
Only hydrogen has un-isotopic atoms without a neutron. Hydrogen can sometimes though have one or so neutrons in its isotopes. The other elements must have neutrons to keep the protons from repelling each other in the atom's nucleus.
What causes atoms of the same elements to have different atomic masses?
Elements have a certain number of protons(+), neutrons(0) and electrons(-). The atomic number shows the number of protons and electrons in the element (has to have the same number of each to stay stable). The atomic mass shows the number of neutrons. For example, Hydrogen has an atomic mass of ~1.01 (and an atomic number of 1). That means that it has 1 electron and 1 proton but no neutron (1 proton+0 neutrons=1). Helium has an atomic mass of ~4.00 (and an atomic number of 2). That means that it has 2 electrons, 2 protons and 2 neutrons (2 protons+2 neutrons=4). Hope you can understand. :S
