Neutrons actually don't carry an electrical charge, which is why they are called neutrons because they are "Neutral".
<span>Igneous rock that cools very quickly when it forms may have a texture that is smooth and shiny with no visible grain.</span>
Remember that carbon has 4 electrons in its valence shell meanwhile bromine has 7
So i think the lewis structure would be :
Br
C Br Br
Br
Hope this helps
Answer:
all the elements in the same period have the same valence electrons.
<span>The following is the role of NaCl and EDTA in DNA isolation, hope it helps:
NaCl provides Na+ ions that will block negative charge from phosphates on DNA.
Negatively charged phosphates on DNA cause molecules to repel each other. The Na+ ions will form an ionic bond with the negatively charged phosphates on the DNA, neutralizing the negative charges and allowing the DNA molecules to come together.</span>
