Atomic symbol of aluminum is written as atomic number(13) atomic mass(27).what information do you get from it
*tell me of its right*:(solution;
atomic no=13
atomic mass=27
no. of electrons=13
no. of protons=13
no. of neutrons=A-Z
no. of neutrons=27-13=14
electronic configuration= *idk*!!!!! hep please :(
electronic configuration is 1s2 2s2 2p6 3s2 3p1
The rest of what you wrote is correct. Good work.
@Drbob222
thankyou :)
From the given information:
- The atomic number of aluminum is 13. This tells us the number of protons in the nucleus of an aluminum atom.
- The atomic mass of aluminum is 27. This represents the average mass of all the naturally occurring isotopes of aluminum. The atomic mass is the combined mass of protons and neutrons in an atom.
To find the number of electrons in an aluminum atom, you can use the atomic number, which, in this case, is 13. Therefore, aluminum has 13 electrons.
To calculate the number of neutrons in an aluminum atom, you subtract the atomic number from the atomic mass. In this case, the atomic number is 13, and the atomic mass is 27. So, the number of neutrons is calculated as 27 - 13 = 14.
The electronic configuration represents how the electrons are arranged in energy levels or shells around an atom's nucleus. The electronic configuration of aluminum is as follows:
1s² 2s² 2p⁶ 3s² 3p¹.
In this configuration, the numbers and letters represent different energy levels and sublevels of the atom. The superscript numbers indicate the number of electrons in each sublevel.
Explanation for the electronic configuration of aluminum:
- The first energy level, 1s², can hold up to two electrons.
- The second energy level, 2s² and 2p⁶, can hold up to eight electrons (2 in the 2s orbital and 6 in the 2p orbitals).
- The third energy level, 3s² and 3p¹, can also hold up to eight electrons (2 in the 3s orbital and 1 in the 3p orbital).
To construct the electronic configuration, you fill the energy levels and sublevels in a specific order, following the Aufbau principle and the Pauli exclusion principle.
Note: It's important to mention that the electronic configuration helps us understand the distribution of electrons in an atom, but it may not provide a complete understanding of an atom's properties.
