What is the atomic number of an oxygen atom that has 8 protons in its nucleus?
Atomic Structure
| A | B |
|---|---|
| If an oxygen atom has 8 protons and 8 neutrons in the nucleus, what is the mass number of oxygen? | 16 |
| If an oxygen atom has 8 protons and 8 neutrons in the nucleus, what is the atomic number? | 8 |
| If an atom has 12 electrons, what is its atomic number? | 12 |
What element has 8 protons and 9 Neutrons?
oxygen
What do we call a carbon atom with 8 neutrons?
These atoms are the isotope called carbon-13. Q: Some carbon atoms have 8 neutrons. What is the name of this isotope of carbon? A: Carbon atoms with 8 neutrons have an atomic mass of 14 (6 protons + 8 neutrons = 14), so this isotope of carbon is named carbon-14.
How many electrons are in an oxygen atom?
2, 6
Which element has the highest occupied energy level?
As you know, an element’s valence electrons are simply the electrons located on the outermost energy level, i.e. on the highest occupied energy level. Therefore, you can say that an element located in group 5A has 5 electrons on its highest occupied energy level.
What is the highest energy level that contains electrons This is called the highest occupied energy level?
Valence electrons
How many electrons are in the highest occupied energy level?
seven electrons
How many electrons are in the highest energy level of a sodium atom?
11 electrons
What is the highest occupied energy level for chlorine?
seven
How many electrons are in the highest occupied energy level for sodium?
Once one shell is full, the next electron that is added has to move to the next shell. So… for the element of SODIUM, you already know that the atomic number tells you the number of electrons. That means there are 11 electrons in a sodium atom.
What element has four energy levels?
| Element | Element Number | Number of Electrons in each Level |
|---|---|---|
| Lithium | 3 | 1 |
| Beryllium | 4 | 2 |
| Boron | 5 | 3 |
| Carbon | 6 | 4 |
How many energy levels are there in an atom?
Explanation: Every atom has an infinite number of energy levels available, depending on how much energy has been absorbed. In the ground state, there are seven (known/most-often-seen) energy levels which may contain electrons. The period number is the same as the highest energy level in that period at ground state.
Why is energy quantized?
Energy is quantized in some systems, meaning that the system can have only certain energies and not a continuum of energies, unlike the classical case. This would be like having only certain speeds at which a car can travel because its kinetic energy can have only certain values.
