Usually, for an neutral atom, the number of protons equals the number of electrons. If the atom is positively charged, it means that it has lost a certain number of electrons. For example, the Fe atom has 26 protons so 26 electrons in its neutral form. It can turns into Fe2+, in which case it would have lost 2 electrons. The new number of electrons is then 24. On the other side, Cl has 17 protons and 17 electrons. It can turn into Cl-, in which case it has gained one electron, the new number of electron is 18. Be careful, the number of protons does not change, it is the number of electrons.
Atomic Mass = number of protons + number of neutrons
and more exact:
Mass number = number of protons + number of neutrons
Number of protons = Number of electrons (in a neutral atom)
For a neutral atom, the relationship between the number of protons and the number of neutrons is the same.
the atomic number is the same number as protons and electrons
protons: positive charged particle
electrons: negative charged particle
In an element the no of proton and electron is always equal that's why an element us always neutrally charged.
Generally they are e similar in numbers. That is why atoms are electrically neutral.
They are equal.
charge of atom = protons - electrons
42
They are equal.
5 protons and 5 electrons
There are 30 protons and 30 electrons in zinc
Roentgenium has 111 protons and electrons.
The Element Neon has 10 protons and 10 electrons.
The atomic number and number of protons are always the same in a normal element.
The atomic number is the number of protons the element possesses.
For a neutral atom, the relationship between the number of protons and the number of neutrons is the same.
Indium has 49 protons and electrons.
They are equal.
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
5 protons and 5 electrons
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.
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.
The element lithium has 3 protons and 3 electrons.
There are 30 protons and 30 electrons in zinc
Roentgenium has 111 protons and electrons.
