1) What is the ground state electron configuration for Oxygen (O)?
2) What is the excited state electron configuration for Oxygen (O)
Help please

Answers

Answer 1

Answer:

1)Oxygen atoms have 8 electrons and the shell structure is 2.6. The ground state electron configuration of ground state gaseous neutral oxygen is [He]. 2s2. 2p4 and the term symbol is 3P2.

Explanation:

2)If the element were to become excited, the electron could occupy an infinite number of orbitals. However, in most texts the example will be the next available one. So for oxygen, it might look like this: 1s22s22p33s1 - where the valence electron now occupies the 3s orbital in an excited (i.e. not ground) state

What is the difference between magnetic stripping and magnetic field reversal?

Answers

Magnetic stripes are evidence of the magnetic field reversal. It's sort of like saying that bear tracks in the snow are evidence that a bear walked by.
Magnetic stripes on the seafloor are formed when new ocean crust is formed. As the magma erupts from the mid-ocean ridges and cools to form rock any minerals containing iron will be oriented in the direction of the magnetic field. When the Earth's magnetic field reverses (every million years or so) the new rock that gets formed will have its magnetic minerals oriented in the opposite direction. This results in a series of magnetic stripes in the rock on the seafloor. (Think of it kind of like a bar code.)
Because new ocean floor is being formed on both sides of mid-ocean ridges and spreading away from the ridges as even newer seafloor is formed, there are symmetric stripes on each side of the ridge. This led to some of the early evidence of tectonic plate motion.

What is the lewis electron dot diagram?

A lewis electron dot structure is used to represent the number of bonds, the bonding atoms, and the lone pairs left in the atoms in the molecule.

Lines are shown between atoms that are bonded to one another and excess electrons or lone pairs are represented as dot pairs and are placed next to the atoms.

As the valence electrons of each chlorine atom are equal to seven from the electronic configuration of the chlorine atom.

First, the total number of valence electrons in a chlorine molecule is 7 + 7 = 14.

As each chlorine atom needs only one electron to complete its octet. As the octet completes, the rest of the electrons are assigned as the lone pairs of atoms. Therefore, each chlorine atom has three lone pairs of electrons on it.

It's important to remember that elements are

Answers

No, unless you're doing some sort of course where they demand that you do. It's useful to remember the general features of the periodic table (what each block is, where they are in relation to each other, roughly where the most common elements are), but memorizing the entire thing would simply be a mnemonic exercise

Explanation:

You place 12.0 milliliters of water in a graduated cylinder. Then you add 15.0 grams of metal to the water and the new water level is 13.91 milliliters. What is the density of the metal in grams per milliliter?

Answers

Answer:

The answer is 7.85 g/mL

Explanation:

The density of a substance can be found by using the formula

[tex]density = \frac{mass}{volume} \\ [/tex]

volume = final volume of water - initial volume of water

volume = 13.91 - 12 = 1.91 mL

We have

[tex]density = \frac{15}{1.91} \\ = 7.853403141...[/tex]

We have the final answer as

7.85 g/mL

Hope this helps you

What does electronegativity measure

Answers

Electronegativity is a measure of an atom's ability to attract shared electrons to itself. On the periodic table, electronegativity generally increases as you move from left to right across a period and decreases as you move down a group.
