How many valence electrons does nitrogen z equals 7 have?
Five: When z equals 7, the total number of electrons must also be 7, but 2 of them are in the filled inner shell of a nitrogen atom and therefore are not valence electrons.
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 if the number of protons and the number of electrons it has are the same.
Which element is the exception to the rule that the number of electrons equals the atomic number?
Helium
When you subtract the atomic number from the atomic mass it will give you the number of what?
the protrons, neutrons and electrons in a atom
What does the sequence in each period represent in relation to electrons?
The sequence in each period represents in relation to electrons is that as you look from left to right on the periodic table, you see a pattern; an increase of the atomic number. The number of electrons equals the number of protons, and the number of protons equals the atomic number.
Does valence electrons equals number of protons?
YES!!!!

How do you calculated electrons?
electron equals the atomic number
How many electrons dose a nitrogen atom have?
8 electrons which equals the atomic number
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 if the number of protons and the number of electrons it has are the same.
Carbon has six electrons in its valence shell True or False?
The number of valence electrons equals an atoms main group number. Carbon is in group 4, therefore carbon has 4 valence electrons.
What is the atomic element if its m shell electrons equals to sum of k and l shell electrons?
rubidium
How an atom valence electrons configuration determine its place on the periodic table?
the valence electron number equals the group number. the principal energy level equals the period number it's located in.
The atomic number of an element equals the number of what atomic particles?
Atomic number = number of protons = number of electrons (in the neutral state)
What does the atomic number equal of an element?
The atomic number of an element equals the number of protons in the element.
The number of electrons in an atom of iodine is?
Iodine has 53 electrons. The atomic number equals the number of protons in an atom, and since iodine is neutrally charged, it also equals the number of electrons.
Which element is the exception to the rule that the number of electrons equals the atomic number?
Helium
