How do you determine the number of valence electrons if you know the group no of elements?
valence electrons are electrons at the outermost shell as we all know, group in PE can be determined by looking at the valence electron thus if it is in group 1..then the valence electron is 1
When is an atom neutral When mass number equals number of protons equals number of electrons or when atomic number equals number of protons equals number of electrons?
An atom is neutral when the number of protons in the nucleus equals the number of electrons surrounding the nucleus. This means that the atom has no overall charge, as the positive charge of the protons is balanced by the negative charge of the electrons. The mass number, which is the sum of protons and neutrons, does not necessarily impact the neutrality of the atom.
How many electrons are in the mass number of 111 and protons of 50?
There are 50 electrons. In a neutral atom, the number of electrons equals the number of protons.
What equals to the number of protons plus the number of electrons?
2 * Z
How many valence electrons does bromine Br atomic no equals 35 have?
Bromine, with an atomic number of 35, has 7 valence electrons. This is because bromine is in Group 17 of the periodic table, also known as the halogen group, which has 7 valence electrons.
Does valence electrons equals number of protons?
YES!!!!

Why do you have groups on the periodic table of elements?
The groups on the periodic table directly correspond to the amount of valence electrons in the outer shell of the elements shown. For example in Group 8 (gases) they all have full valence electrons which equals 8 in the outershell. An element in group 1 only has 1 valence electrons like hydrogen or sodium.

How many electrons are in the mass number of 111 and protons of 50?
There are 50 electrons. In a neutral atom, the number of electrons equals the number of protons.
How do the numbers of protons neutrons and electrons for an element compare?
In the neutral state, all atoms of the same element contain equal numbers of protons and electrons. However, most elements have atoms with different numbers of neutrons. These are called isotopes.
In a neutral atom the number of electrons equals the number of what?
The number of electrons should equal the number of protons, otherwise you have an ion.
What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
17 protons equals how many electrons?
17 protons in an atom would equal 17 electrons to maintain a neutral charge.
How many protons and electrons are contained in an atom of element ruthenium?
An atom of ruthenium contains 44 protons and 44 electrons. This is because the number of protons in an atom determines its identity, and for a neutral atom, the number of protons equals the number of electrons.
What is a metal with 25 electorns?
manganese. In the future look at the table of elements with the top number (called the atomic number: which is the number of protons, which also equals the number of electrons,) to see the number of electrons
What is the number of protons in a neutral atom equal to?
The number of protons equals the number of electrons in an uncharged atom.
