I'm sorry, but I need more context or information in order to provide step-by-step instructions for these questions. Could you please provide more details or clarify what you are asking?

To answer these questions, you need specific information about the "new atom" or the decay being referred to. If you have the necessary information, you can follow these steps to find the answers:

1. Atomic mass: The atomic mass of an atom is the sum of the number of protons and neutrons in its nucleus. To find the atomic mass of the new atom, you would need to know the number of protons and neutrons present. You can typically find this information in a periodic table or by researching the specific atom or isotope being referred to.

2. Atomic number: The atomic number of an atom indicates the number of protons in its nucleus. It helps to identify the element. To find the atomic number of the new atom, you need to know its elemental identity or the number of protons present in its nucleus. This information can also be found on a periodic table or through research.

3. Symbol: The symbol of an atom is a one- or two-letter abbreviation used to represent the element. It is typically derived from the name of the element. The periodic table is the best resource to find the symbol of the new atom. Each element has a unique symbol.

4. Type of decay: Determining the type of decay demonstrated requires more context or specific information about the decay process being referred to. There are several types of radioactive decay, such as alpha decay, beta decay, gamma decay, and others. To identify the type of decay, you may need to examine certain characteristics of the decay process, such as the emission of particles, change in atomic number, or energy levels. It could also be helpful to refer to scientific literature, textbooks, or online resources for more information about the specific decay process being observed.

Remember, having more information about the specific scenario or atom in question will provide a more accurate answer to these questions.
