What else can I help you with?
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).
An alpha particle is equivalent to a hydrogen nucleus. True False?
False. An alpha particle is equivalent to a helium-4 nucleus.
He is the chemical symbol for what?
He is the atomic symbol for Helium
Is the particle with a plus 2 charge a an alpha particle b a gamma ray or c a beta ray?
a. an alpha particle
What is the scientific name for He?
The symbol He represents the chemical element Helium.
What radiation releases a helium particle?
Alpha radiation is essentially a Helium nucleus (not the whole atom, apha particles don't have electrons on them). An alpha particle is just two protons and two neutrons and as a result they also have a relative charge of +2.
What particle consists of two protons and two neutrons it is the same as a helium nucleus release of a what particle by an atom decreases the atomic number by 2 and the mass number by 4?
The particle that consists of two protons and two neutrons, equivalent to a helium nucleus, is an alpha particle. When an atom releases an alpha particle, its atomic number decreases by 2 and its mass number decreases by 4.
The nuclear fusion of a helium-3 nucleus and nuclide X releases an alpha particle and a positron Identify nuclide X?
The nuclide X would be tritium (hydrogen-3). In the described fusion process, a helium-3 nucleus and tritium combine to form a stable helium-4 nucleus along with the release of an alpha particle (helium-4 nucleus) and a positron.
What is an alpha particle equivilent to?
An alpha particle is the same as a helium-4 nucleus.An alpha particle is the same as a helium-4 nucleus.An alpha particle is the same as a helium-4 nucleus.An alpha particle is the same as a helium-4 nucleus.
What radioactive particle is the size of a helium nucleus?
alpha particle
What element has atomic structure similar to an alpha particle?
The element with atomic structure similar to an alpha particle is helium. An alpha particle consists of two protons and two neutrons, the same as the nucleus of a helium atom.
Why is an alpha particle sometimes referred to as a helium nucleus?
An alpha particle is made up of two protons and two neutrons; this is what a helium nucleus is made up of as well.
What happens to the atomic number when the nucleus releases a beta particle?
When the nucleus releases a beta minus particle the atomic number increase with 1.When the nucleus releases a beta plus particle the atomic number decrease with 1.
The nucleus of a helium atom is called?
The nucleus of a helium atom is called an alpha particle. The electromagnetic waves emitted by a nucleus are called gamma rays.
What are some unusal facts about helium?
- It's the lightest noble gas. - It's the second most abundant element in the universe. - Liquid helium is a superconductor. - The nucleus of a helium atom is equivalent to an alpha particle. - Its extreme stability is the reason why its fusion from hydrogen releases so much energy. - It makes you talk funny when you inhale it.
The nucleus of a helium atom is identical to what?
The nucleus of a helium atom is identical to an alpha particle, which consists of two protons and two neutrons.
Hydrogen is to a proton as helium is to?
an alpha particle
