Since you want atomic (rather than molecular) anions AND 9 protons only the element with atomic number 9 is possible, i.e. Fluorine. This has really only one anionic state though, -1. So I can only suppose you mean either:
- transient unstable anions
- synthetic isotopes of Fluorine (also unstable)
- molecular rather than atomic anions
In the latter case (most likely) you could have as well as F- also e.g. NH2- or OH- as molecular (not atomic) anions with 9 protons in total.

What are the number of protons in florine?
The atomic number of Oxygen is 8, which is also the number of protons.
What Atomic number of element has 9 protons and 10 neutrons?
The atomic number of an element is equal to the number of protons in its nucleus. Given that the element has 9 protons, its atomic number is 9. Therefore, the element in question is fluorine (F), which has an atomic number of 9.
What if fluorine's atomic number?
Fluorine's atomic number is 9, meaning it has 9 protons in its nucleus.
What is the atomic mass of a number that have 8 protons and 9 neutrons?
The atomic mass of an atom can be calculated by adding the number of protons and neutrons together. In this case, an atom with 8 protons and 9 neutrons would have an atomic mass of 17 atomic mass units (amu).
An element has 4 protons 5 neutrons and 4 electrons What is the atomic mass of the element?
The atomic mass of an element is the sum of its protons and neutrons. In this case, the atomic mass would be 4 protons + 5 neutrons = 9 atomic mass units.
What are the chemical symbols for three different atomic anions that all have 9 protons?
Chlorine anion: Cl-, Fluorine anion: F-, Oxygen anion: O2-
How many protons are found in a atom of fluorine?
The atomic number of fluorine is 9. So there are 9 protons
How many protons are represented in an atom which has an atomic number of 9 and an atomis mass of 19?
An atom with an atomic number of 9 means it has 9 protons. The atomic mass of 19 indicates the total number of protons and neutrons in the nucleus, so if the atom has 9 protons, the remaining mass comes from neutrons (19-9=10 neutrons).
What element has 9 protons?
The number of protons is equal to the atomic number. Fluorine's atomic number is 9, so Fluorine has 9 protons.
How many protons does Fhave?
An atom's atomic number gives its number of protons. Fluorine's atomic number is 9. Thus, fluorine has 9 protons.
Number of protons in fluorine atom?
An atom's atomic number gives us its number of protons. Fluorine's atomic number is 9. Thus, it has 9 protons.
What are the number of protons in florine?
The atomic number of Oxygen is 8, which is also the number of protons.
An isotope of fluorine has a mass number of 19 and an atomic number of 9. how many protons are in this atom?
There are 9 protons in this fluorine atom because the atomic number (9) represents the number of protons in an atom.
What is the atomic number of an element whose atoms have 9 protons and 10 neutrons?
The atomic number is the number of protons. It is also the number of electrons. The atomic mass equals the protons and neutrons together/weight of the nucleus. So, the atomic number would be nine, because there are 9 protons. The atomic mass would be around 19, because there would be 9 protons and 10 neutrons in the nucleus. The element you are talking about is actually Fluorine, and on the periodic table it says that the atomic mass is 18.9984032. This is because the atomic mass is usually never an exact amount. You can round this decimal place to 19, anyway.
How Many protrons are in fluorine?
Flourine has the atomic number of 9. The atomic number determines the number of protons in an atom of the element, so there are 9 protons.
How are atomic numbers and protrons related?
The atomic number of any element is equal to the number of protons in its nucleus. For example, fluorine (F) has an atomic number of 9. This means it has 9 protons.
What Atomic number of element has 9 protons and 10 neutrons?
The atomic number of an element is equal to the number of protons in its nucleus. Given that the element has 9 protons, its atomic number is 9. Therefore, the element in question is fluorine (F), which has an atomic number of 9.
