It depends on whether the beta decay is beta- or beta+.
The alpha emission reduces the atomic number by 2. Beta- increases the atomic number by 1 while beta+ decreases the atomic number by 1. You do the math.

What happens to a particle of a substance when it expands?
individual particles do not expand, when a substance expands it is the dead space between the particles that expands and the particles begin to move around (assuming the substance was solid to begin with). If a particle did expand it would loose cohesion and break apart (possibly creating an atomic reaction depending on how it was expanded)
Each fundamental atomic particle has an opposite particle A collision of these opposites will result in the annihilation of each particle These types of particles are referred to as?
Anti-matter. Antimatter.
What element is formed when Ra emits an alpha particle?
Next element in the periodic table ie Actinium.
What is produced when a radioactive element decays?
Energy, various sub-atomic particles, a different element.
Each fundamental atomic particle has an opposite particle. A collision of these opposites will result in the annihilation of each particle. What are these types of particles called?
Anti-particles. In the case of the (normal negatively-charged) electron, the anti-particle has a specific name; the positron. Since normal particles are the building blocks of matter, a collection of anti-particles are termed "anti-matter".
What happens to the atomic number of an element if it emits 1 alpha particle and 1 beta particles?
It drops 2
The smallest part of an element that act like an element?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
Which particle determines the atomic number of an element?
The atomic number of an element is determined by the number of protons.
What is the name of the smallest paricle of an element that has the properties of that element?
An atom is the smallest particle of an element that has the properties of that element. The atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element. No Sub-Atomic Particles have any characterisitics of an element. It is the collective arrangement of electrons and protons (and usually neutrons) which gives an element its characteristics. An atom is the smallest particle that has elemental characteristics.
What is the smallest amount of an element that still retains the characteristic of that element?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
The smallest part of an element that retains the elements characteristics?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
What happend to the atomic number of an element which emits alpha particle and two beta particle?
THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.
What is the smallest unit of an element that still can be identifled as a specific element?
The atom is the smallest particle of an element that retains it's characteristics. Sub-atomic particles such as protons, neutrons and electrons form the atom and it is the amount of each of these sub-atomic particles that make the element that element.
What subatomic particle is related the atomic number of an element?
protons, no. of protons is equal to the atomic number of an element.
What is the smallest unit of an element that maintains of that element?
The Atom is the smallest particle of an element that has characteristics of that element. The Atom consists of a certain amount of electrons, protons and usually neutrons. The amount of each of these sub-atomic particles is what makes an element into a Atom.
What of these subatomic particles are represented by atomic number?
This particle is the proton.
What sub atomic particle determines what the element is?
Proton
