What subatomic particle determines if an element is an isotope or not?
The neutron; the proton determines the element of the atom, but different atoms of the same element can have different atomic masses, due to the different number of neutrons of the atoms. Atoms of same element having same number of protons but different number of neutrons are called Isotopes. Thus, neutron determines the isotope of an atom.
What is the protons neutrons and electrons of helium?
The number of protons in an element is always the same as the atomic number, which is 2 in the case of helium. (The atomic number is assigned based on the number of protons in an element.) In a neutral atom (one with no charge), the number of electrons equals the number of protons, so it will be 2 electrons also. However, the number of neutrons will vary depending on the isotope (atoms of the same element with different numbers of neutrons). There are two stable isotopes of Helium, 3He and 4He, having 1 neutron and 2 neutrons respectively. Most helium is helium-4, and helium-3 is found as only about one atom in a million.See link below for more information on Helium, as well as the related question below that will show you how to find the number of protons, neutrons, and electrons in any atom.
Neutrons and what almost have the same mass?
A neutron and a proton almost have the same mass. A neutron and 1,840 electrons almost have the same mass.
How do you find the number of neutrons when an element has a charge?
Neutrons are neutrally charged. It is not possible to determine the charge of an atom through knowledge of the number of neutrons contained within its nucleus. Consider hydrogen, for example. It has no neutrons, one proton, and one electron. Its charge is neutral. Deuterium is hydrogen with a neutron, but also has the same charge. Tritium is hydrogen with two neutrons within its nucleus--again, no charge.
Subatomic particles that have negative charges are?
In the atom these particles are the electrons.
What three things is each element composed of?
Protons, neutrons (both in the nucleus) and electrons.
What is tha neutron for calicum?
An atom contains protons, neutrons, and electrons. The electrons are tiny. They can be found in a fast-moving cloud, orbiting the nucleus. Each electron has a charge of -1. The nucleus contains the protons and neutrons, which are packed tightly together. The protons each have a charge of +1, and the neutrons have a charge of zero. The mass number of an element is the number of protons and the number of neutrons added together. Since the number of protons is equal to the atomic number of the element, the number of neutrons can be found by subtracting the atomic number from the mass number.
How many neutrons are in helium?
He-4 isotope has 2 neutrons. He-3 isotope has 1 neutron
How do you tell the number of neutrons in an element?
Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.
What is the use of neutrons protons and electrons?
Neutron are what keeps the nucleus together. Protons are what decides the kind of element which the atom is and the electrons decide the charge of the atom.
If an element has 12 protons and 13 neutrons how many electrons dose it have?
12 electrons. Remember, electrons and protons must be balanced in charge; neutron number may vary.
What is the only particle that can change in number for an isotope?
The Neutron- An element with the same number of protons and electrons, but with a different number of neutrons per atom than the original element is called an "isotope". An isotope will have, for all intensive purposes, about the same chemical and physical properties as the original element. Isotopes are written as the element, followed by a dash, then the number of neutrons in one atom of that isotope (Carbon-13 is an isotope of carbon with 13 neutrons per atom)
What is the differences between isotope and element?
Regular elements contain regular neutron number and the same number of protons and neutrons. Isotopes have different neutron numbers than the original element, but the same number of protons and electrons.
What parts of an atom has no charge protons neutrons electrons or the nucleus?
neutrons, just think neutron = neutral
Which of the following is not found in the nucleus of a atom?
Electrons are not components of the atomic nucleus.
What is the element actinium proton electron neutron?
The most common isotope of actinium, Ac-227, has 89 protons and electrons and 138 neutrons.
Protons neutrons and electrons of beryllium?
what do you mean the "colors" they don't have any specific colors What we perceive as colors is due to how the material interacts with light. A proton is a proton. An electron is an electron. A neutron is a neutron. They don't change character depending on which element they are in.
