An alpha particle is, essentially, a helium nucleus.
This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.
So the atomic number of an alpha particle would be 2.
It's also not neutral, and would have a 2+ charge.
The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.
All alpha particles are helium nuclei, so they all share the same properties.

What does an atoms atomic number tell about the atom?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What does the atomic number of the atom tell us?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What characteristics must two elements share if they are in the same period?
Elements in the same period share the same number of electron shells. This means they have similar atomic sizes and properties because they have the same number of electron shells determining their size and behavior.
What four elements have chemical propeties most similar to fluorine's (atomic number 9)?
The four elements that have chemical properties most similar to fluorine are chlorine (atomic number 17), bromine (atomic number 35), iodine (atomic number 53), and astatine (atomic number 85). These elements belong to the halogen group (Group 17) of the periodic table, which share similar reactivity and properties due to their comparable electron configurations. Like fluorine, they tend to form similar types of compounds, particularly halides, and exhibit high electronegativity.
If an element with the atomic number of 119 was discovered which elements would share the same caracteristics?
If an element with atomic number 119 was discovered, it would likely belong to the same group as other elements in Group 19 of the periodic table. Elements in the same group share similar characteristics due to their similar electron configurations. Additionally, it may have similar properties to other superheavy elements in the same period, due to its high atomic number.
What same elements have the same atomic number?
though your question is unclear, each element has its own atomic number. every sample of Sulfur (S) that exists has the atomic number of 16. No different elements share the same atomic number.
What does the atomic number tell us about an atoms?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.

Elements in the same period share the same number of electron shells. This means they have similar atomic sizes and properties because they have the same number of electron shells determining their size and behavior.
Who has a minecraft alpha account they'll share with you email you at quaellen67gmailcom?
nobody has an account they will share.
The atomic number is the same as the number of these particles?
In any atom, the number of protons will equal the number of electrons, but only in a neutral atom. Remember that most atoms loan, borrow or share electrons, so the number of protons will not be equal to the number of electrons in all cases. In review, only in a neutral atom will the number of protons equal the number of electrons.
What number in the nucleus makes the elements unique?
That would be the Atomic number. It tells you how many protons are contained in the nucleus of an atom. No two elements could share this number.
What four elements have chemical propeties most similar to fluorine's (atomic number 9)?

Like fluorine, they tend to form similar types of compounds, particularly halides, and exhibit high electronegativity.
What is meant by the statement -this element has 3 isotopes?
The statement means that the element in question has three different forms (isotopes) with varying numbers of neutrons in their atomic nuclei. These isotopes of the element share the same number of protons and electrons but have different atomic masses due to the differing number of neutrons.
If an element with the atomic number of 119 was discovered which elements would share the same caracteristics?
If an element with atomic number 119 was discovered, it would likely belong to the same group as other elements in Group 19 of the periodic table. Elements in the same group share similar characteristics due to their similar electron configurations. Additionally, it may have similar properties to other superheavy elements in the same period, due to its high atomic number.
What are the differences between groups and periods?
Groups consist of elements listed in the same column. These elements share similar chemical properties, such as number of valence electrons. Periods are the rows of elements. These elements do not share chemical properties, as periods are organized by increasing atomic number (number of protons).
