The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Therefore, we group elements whose atoms have the same number of valence electrons together in the Periodic Table. ... This tendency is called the octet rule, because the bonded atoms share eight valence electrons.
Answer:
1 a person sings into a microphone
2 the sound is converted into an electrical signal
3 the analog signal is converted into a digital signal made of many samples of the digital sound
4 the samples of the sound is converted into 1s and 0s
5 the digital pattern is converted to a medium such as a hard disk or flash drive
Explanation:
Answer:
D.
Explanation:
You try to get 8 electron on the outermost "shell" so you have no left over or "valence" electrons.
The atoms on the products side are bonded into different molecules from the atoms on the reactants side is the chemical changes occured.
<u>Explanation:</u>
- The reaction commences when the compounds on the reactant side are ready to react to give the product.
- The reaction initiated by the transfer of electrons and molecules from the reactants to give the combined product of both the reactants.
- It is a process on which there will be rearrangement in the structure of molecules of a substance from its physical for more chemical form.
- In the above picture it shown that the red molecules combined with the white molecules additionally and changed the structure.
Answer:
148 grams of relative atomic mass
Explanation:
magnesium atomic mass : 24
nitrogen : 14
oxygen : 16
24 × 1
14 × 1 × 2
16 × 3 × 2
24 + 28 + 80 = 148 grams
