Answer:
The first two electrons is placed in the 1s orbital. The next 2 electrons for magnesium go in the 2s orbital.The next six electrons will go in the 2p orbital. We’ll put six in the 2p orbital and then put the remaining two electrons in the 3s.Therefore, the Magnesium electron configuration will be 1s22s22p63s2.
What is the electron configuration of Magnesium 12?
Explanation: the Magnesium electron configuration will be 1s² 2s² 2p6 3s². Magnesium has atomic number 12.
What is e9 class configuration?
Electronic configuration is defined as the distribution of electrons into the orbitals of an atom. Every neutral atom consists of a fixed number of electrons which is equal to the number of protons and is called the atomic number.
What is the electronic configuration of MN 25?
Explanation: The electron configuration of manganese, atomic number 25, is 1s2222p63s23p63d54s2 .
What is the electronic configuration of 15p?
Therefore the Phosphorus electron configuration will be 1s22s22p63s23p3. The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom. This makes it easier to understand and predict how atoms will interact to form chemical bonds.
What is the electron configuration of 13 AL?
Aluminum (atomic number 13), with 13 electrons and the electron configuration [Ne]3s23p1, is analogous to its family member boron, [He]2s22p1.
What is the electronic configuration of Cu 29?
Element Cu has an atomic number 29. The electronic configuration should be: 1s2 2s2 2p6 3s2 3p6 4s2 3d9. However, the actual electronic configuration is 1s2 2s2 2p6 3s2 3p6 4s1 3d10 or [Ar] 3d104s1. This is because the half-filled and fully filled configurations (d5 d10 f7 f14) have lower energy or more stability.
What is the electronic configuration of 11na?
Step-by-step explanation: When we write the configuration we’ll put all 11 electrons in orbitals around the nucleus of the Sodium atom. In writing the electron configuration for sodium the first two electrons will go in the 1s orbital. Therefore the sodium electron configuration will be 1s22s22p63s1.
What has 15 protons and 16 neutrons?
if you look at the periodic table, phosphorus has 15 electrons and protons, and 16 neutrons.
