How do you use the symbol of an element to work out the number of protons neutrons and electrons in an atom?

Apart from using the symbol to look it up on the Periodic Table, you can't, and even that will not give you the number of neutrons directly.

What is the number of protons plus the number of electrons?
The number of protons plus the number of electrons isn't a recognized figure in chemistry. The number of protons is the atomic number of an element. The number of electrons is the same as the number of protons except when the element is an ion. An ionic compound results in one or more electrons moving from one element to another element. Although this is a simplification, it can be described as the atom gaining or losing electrons. The number of protons plus the number of neutrons is the atomic weight of an element.
Which chemical element has 177 neutrons 77 protons and 77 electrons?
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
What do all atoms of an element have?
They all have protons and electrons. And all but hydrogen have neutrons as well. The number of protons is an element's atomic number. Assuming the atom is neutral, this will also be the number of electrons. The number of neutrons can vary among isotopes of the same element.
If the atomic number of an element is five how many protons does the element have?
Neutrons do not affect the neutrality (or charge) of an atom; protons and electrons do. In order to be neutral, the number of protons must be the same as the number of electrons.
What can be determined by looking at the atomic number of an element?
the number of protons in an atom and the number of electrons in an atom
What are the number of protons neutrons and electrons in an element?
Number of protons = Number of electrons = Atomic number Number of neutrons = Atomic number - Number of protons
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
Neutral atoms of the same element can differ in their number of what?
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
How many neutrons and electrons are in the element americium?
Americium has 95 protons and electrons. Number of neutrons: atomic mass of an isotope - number of protons
Protons electrons and neutrons in any given atom?
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
How many protons neutrons and electrons does si-28 have?
Silicon 28 (28Si) has 14 protons, neutrons and electrons.

How many protons electrons and neutrons in chromium?
There are 24 protons in Chromium (Cr). The atomic number of an element is the same as the number of protons.
What are the basic properties of an element?
the number of neutrons, protons, and electrons
How many neutrons and electrons are in the nucleus of an atom?
The atomic number of a chemical element is equal to the number of electrons or protons. The number of neutrons = Atomic weight of an isotope (rounded) - atomic number of the element (or the number of protons)
Which chemical element has 177 neutrons 77 protons and 77 electrons?
Atoms are defined by the number of protons in the nucleus; therefore, we can tell what element it is by the number of protons (the information about the neutrons and electrons is unnecessary). An atom with 77 protons is iridium.
Does all the isotopes of an element have the same number of neutrons?
No, the number of neutrons vary, but protons and electrons are static among an element.
