All you need is a Periodic Table. The number of protons is the same as the atomic number - always. The periodic table is organized by increasing atomic number, so finding the number of protons an atom of an element has becomes an exercise of glancing at the table. For example, hydrogen is the first element on the periodic table, with the atomic number of one. This means that it has one proton. The second element on the table (He) with the atomic number of two has two protons, etc.
In a neutral atom, the number of electrons will equal the number of protons. If the number of each subatomic particle is the same, then the atom has a net charge of zero: neutral. If the atom is charged, then it is specifically called an ion. This occurs when there are more protons than electrons or more electrons than protons. To find the number of protons based on charge, just take the element's atomic number (or number of protons) and subtract the value of the charge. For example, lithium forms the ion Li+1. It's atomic number is 3 (meaning it has 3 protons) and 3-1 = 2 electrons.
What else can I help you with?
How many electrons and protons lithium have?
The element lithium has 3 protons and 3 electrons.
How to find the total electron in element?
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
What are the number of protons and electrons found in an element called?
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
How many electrons in an atom with 49 protons?
A neutral atom with 49 protons has 49 electrons.
How many protons and electrons are in element with an atomic number?
An element's atomic number is equal to the amount of protons in that element. Each atom has a different number of protons and electrons present in their make-up.
If element X has 72 protons how many electrons does it have electrons?
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
How many protons and electrons are in the element boron?
5 protons and 5 electrons
How many electrons and protons lithium have?
The element lithium has 3 protons and 3 electrons.
What are the number of protons and electrons found in an element?
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
How many protons and electrons in fluorine?
Fluorine has 9 protons and 9 electrons. The number of protons determines the element's identity, while the number of electrons is equal to the number of protons in a neutral atom.
The atomic number of an element is what?
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
How to find the total electron in element?
To find the total number of electrons in an element, first you need to look up the element's atomic number. That number tells you how many protons are in the element. Then, look up the net charge of the element. The number of protons subtracted by the elements net charge will give you the number of its electrons.
How many protons and electrons in 107Ag?
Silver-107 has 47 protons and 47 electrons. This is because the number of protons equals the element's atomic number, and in a neutral atom, the number of electrons also matches the number of protons.
What are the number of protons and electrons found in an element called?
the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
What tells you how many protons and electrons an element has?
The atomic number = Number of protons = Number of electrons
How many electrons does the element neon?
The Element Neon has 10 protons and 10 electrons.
How many protons and electrons does xenon have?
The element xenon (Xe) has 54 protons and 54 electrons.
