What else can I help you with?
What is equal to the number of protons which is equal to the number of electrons?
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
What is the total number of valence electrons in a fluorine atom you n the ground state?
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
What identify the number of protons neutrons and electrons in the atom.?
The number of protons in an atom is equal to its atomic number, which identifies the element. Neutrons are found by subtracting the atomic number from the mass number. For a neutral atom, the number of electrons is equal to the number of protons.
How do you find out the amount of electrons in an atom?
The number of electrons in an atom is equal to its atomic number, which is the number of protons in its nucleus. This is because atoms are electrically neutral, so they have an equal number of protons and electrons. You can find the atomic number of an element on the periodic table.
What indicates the number of an electron in a neutral atom?
The number of an electron in a neutral atom is indicated by the atomic number, which is equal to the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is the same as the number of protons.
Does the valence electrons equal the number of protons?
No, the number of valence electrons does not necessarily equal the number of protons in an atom. The number of valence electrons is determined by the group number of the element in the periodic table, while the number of protons is the atomic number of the element.
Are valence electrons the number of protons?
Only for hydrogen and helium are these two numbers the same. All other elements have at least two non-valence electrons, and the total number of electrons must be equal to the number of protons. Therefore, in all elements except hydrogen and helium, the number of valence electrons is less than the number of protons.
What is the valence number for helium?
He has 2 valence electrons. Look on a periodic table. It will show He only has 2 protons and the number of protons and electrons is equal. It is an exception to the rule of group numbers corresponding to valence numbers.
What is the number of protons in the nucleus or the number the electrons in the energy levels called?
The number of protons in the nucleus is called the atomic number and is equal to the number of electrons in a neutral atom.
Does an element's number of valence electrons equals the element's number of protons?
Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.
In an atom the number of what is equal to?
In an atom the number of electrons is equal to the number of protons. That is, in the case of an un-ionized, non valence bonded molecule... If the atom were ionized, it could have fewer or less electrons. If the atom were part of a valence bonded molecule, it could be sharing valence electrons with other atoms.
How the atomic number related to the core electrons?
The atomic number represents the number of protons in an atom's nucleus, which is also equal to the number of electrons in a neutral atom. Core electrons are those that are closest to the nucleus and are not involved in chemical bonding. The number of core electrons in an atom is equal to the difference between the atomic number and the number of valence electrons.
How many valence electrons does a neutral magnesium atom have?
If its a neutral atom, then it will have the same number of electrons as protons. Magnesium has 12 protons and 12 electrons.
Do valence electron equal the number of protons?
The number of electrons usually does not equal the number of protons. Valence means outermost. In an electrically neutral atom (which in Gen Chem is the only atoms you will be dealing with) the number of outermost electrons usually does not equal the number of protons. Chlorine has 7 valence electrons but it has 17 protons and if it is electrically neutral (which in gen chem it almost always is) it has 17 electrons. Gen Chem 1: it has 2 electrons in the first shell then it has 8 electrons in the second shell then it has 7 electrons in the outermost shell Gen Chem 2: it has 2 electrons in the 1s orbital then it has 2 electrons in the 2s orbital then it has 6 electrons in the 2p orbital then it has 2 electrons in the 3s orbital then it has 5 electrons in the 3p orbital
How many electrons does aluminum with an atomic number of 13 have in its valence shell?
None. the positive charges on the 13 protons and the negative charges on the 13 electrons cancel each other out
How can you use the periodic table to find the number of protons in one atom of an element?
valence electrons is the same as the number as the last digit in the group :)
Do protons and electrons have the same number?
Yes, the atomic number is equal to the number of protons. The number of protons is also equal to the number of electrons
