Answer:
The metalloids are a unique group of elements that share properties of both metals and nonmetals. They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.
Elements: Arsenic
Answer:
A
Explanation:
Chlorine has one valence electron
Hence one chlorine atom reacts with 2 atoms of lithium
And also reacts with 3 atoms of boron
Answer:
Explanation:
There are principles that guides the distribution of electrons into the energy levels in an atom. Some of the principles are:
1. The maximum number of electrons in the orbitals of sublevels are:
2 electrons for s-sublevel with one orbital
6 for p-sublevel with 3 orbitals
10 for d- sublevel with 5 orbitals
14 for f-sublevel with 7 orbitals.
The maximum number of electrons in an orbital is 2.
2. Aufbau principle: it states that sublevels with lower energy are filled up before those with higher energy. Sublevels have pattern of filling.
3. Pauli exclusion principle: it states that no two electrons can have the same set of the four quantum numbers.
4. Hund's rule of maximum multiplicity: electrons goes into degenerate orbitals of sub-levels singly before pairing starts.
Answer:
In the first part of Lesson 1, it was mentioned that sound is a mechanical wave that is created by a vibrating object. The vibrations of the object set particles in the surrounding medium in vibrational motion, thus transporting energy through the medium.
