# What Does The Electron Configuration Of An Element Show?

## How do you find electrons in an isotope?

To find the number of electrons, add the opposite of the charge imbalance to the number of protons.

For example, if an isotope has a -3 charge, as with phosphorus (atomic number 15), then the number of electrons is three greater than the number of protons..

## What is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6?

Kr (Krypton) 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. Rb (Rubidium) 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1. Sr (Strontium)

## What is an electron orbital diagram?

Orbital diagrams are pictorial descriptions of the electrons in an atom. Three rules are useful in forming orbital diagrams. According to the Auf Bau Principle, each electron occupies the lowest energy orbital. The Pauli Exclusion Principle says that only two electrons can fit into an single orbital.

## What two things does the electron configuration tell you about an element?

It tells you how many electrons there are in each of the different orbitals (s, p, d, or f) and at which energy level (n= 1, 2, 3, …).

## How do you find the electron?

The number of protons, neutrons, and electrons in an atom can be determined from a set of simple rules.The number of protons in the nucleus of the atom is equal to the atomic number (Z).The number of electrons in a neutral atom is equal to the number of protons.More items…

## How do we find atomic mass?

Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number.

## What is the color of an electron?

Protons are colored red with a “+” charge. Neutrons are green with no charge. Electrons are blue with a “-” charge.

## What do you call the element from atomic number 57 71?

Lanthanides. What do you call the element series from atomic number 57-71? Silicon.

## What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2?

So, an antimony atom with charge +2 has an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p1.

## What is atomic mass unit explain with example?

An atomic mass unit is defined as a mass equal to one twelfth the mass of an atom of carbon-12. The mass of any isotope of any element is expressed in relation to the carbon-12 standard. For example, one atom of helium-4 has a mass of 4.0026 amu. An atom of sulfur-32 has a mass of 31.972 amu.

## What does P mean in electron configuration?

P orbitals are groups of three orbitals, which means that they can have six electrons total. You write them the same as s orbitals, but never with a 1. That’s because the energy level for 1 is too low for p orbitals. For example, that would mean that boron would have an electron configuration of 1s^2 2s^2 2p^1.

## What are the three rules for writing the electron configuration of elements?

What are the three rules for writing the electron configurations of elements? Three rules—the aufbau principle, the Pauli exclusion principle, and Hund’s rule—tell you how to find the electron configurations of atoms.

## What is the element with the electron configuration 1s22s22p63s2?

element Silicon2 Answers. BRIAN M. The electron configuration 1s22s22p63s23p2 is the element Silicon.

## Does atomic number equal electrons?

The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons. The sum of the atomic number Z and the number of neutrons N gives the mass number A of an atom.

## What is the average atomic mass?

The average atomic mass of an element is the sum of the masses of its isotopes, each multiplied by its natural abundance (the decimal associated with percent of atoms of that element that are of a given isotope). … The atomic number of chlorine is 17 (it has 17 protons in its nucleus).
