Why are all atomic numbers whole numbers?
The atomic number is the number of protons.
How do you get atomic mass?
Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom.--> Atomic Mass = protons + neutrons
178 Au 79 is a of gold?
Assuming there is a blank between "a" and "of," 178Au is an unstable isotope of gold. The 79 is its atomic number (number of protons), and 178 is the atomic mass (number of protons + numbers of neutrons).
What is the number of protons plus the number of neutrons in an atom always a whole number?
The two are counts and so natural numbers. The set of natural numbers is closed under addition.
What parts of an atom are equal to each other?
It depends on what you mean by what parts are equal. Protons and electrons both have the same magnitude of charge with opposite signs and electrons are much less massive than protons. Protons and neutrons are approximately equal in mass but protons have a charge of +e Coulombs while neutrons have a charge of 0. Atoms can often exist with unequal numbers of protons and electrons. Such atoms are called ions and have a negative charge if they have more electrons than protons and positive charge if they have more protons than electrons.
What is a structure consisting of two protons and two neutrons called?
alpha particle
What is a particle that has unequal numbers of protons and electrons?
an ion
Structure consisting of 2 protons and 2 neutrons which is identical to the helium nucleus?
An alpha particle.
Structure consisting of two protons and two neutrons which identical to the heliumb nucleus?
alpha particle
What occurs when a nucleus releases a particle consisting of two protons and two neutrons?
Alpha Decay
Do atoms include molecules electrons elements and protons?
No. Atoms contain protons, neutrons and electrons. An element is a substance consiting of atoms with the same number of protons. A molecule is a particle consisting of two or more atoms covalently bonded to one another.
Positively charged particle consisting of 2 protons and 2 neutrons which is given off by a radioactive substance is called what?
A radiation particle consisting of two protons and two neutrons is called an Alpha Particle. Alpha Particles have the same structure as a Helium nucleus. There are three forms of radiation, Alpha (Helium nucleus), Beta (a lone electron) and Gamma (an Electromagnetic wave).
Particle consisting of 2 protons and 2 neutrons?
Helium Because mass= protons + neutrons Therefore 2+2=4 and the element with mass of 4 is helium Hope this helped
Are alpha particle negative or positive?
An alpha particle is a helium nucleus; it has a charge of +2.
Why is it impossible for helium or hydrogen to emit an alpha particle?
Helium and hydrogen do not emit alpha particles because they contain only one or two protons in their nuclei respectively, which is insufficient for them to emit an alpha particle consisting of two protons and two neutrons. Alpha decay typically occurs in heavier elements with larger atomic numbers where the nucleus is unstable and emits an alpha particle to reach a more stable configuration.
What type of radioactive particle has 2 protons?
An alpha particle has two protons.
An alpha particle is identical to a?
An alpha particle is identical to a helium-4 nucleus, consisting of two protons and two neutrons. It is emitted during the process of alpha decay in certain radioactive elements.
