the first one is metals
Explanation: the last one is b
the first one is metals and the second one is molecule
I just looked in a textbook, hope I could help!
2. Solid, gas, liquid
The majority of elements in the periodic table are classified as metals. The transition metals lie in the center of the table, spanning groups three through 12. These elements are solid at room temperature, except mercury, and have the metallic color and malleability expected of metals.
Hope this helps :)
1. Neutron, proton and electron
2.The number of protons of its atoms
Trust me I'm in highschool chemistry
10 hydrogen atoms + 5 oxygen atoms = 15 atoms
plz vote brainleist
5 + 5 + 5 = 15
A & B
The answer for the first one is A because the proton is found in the nucleus with the neutron
The answer for the second was is B because the Neutrons, protons and electrons are all subatomic particles, as they are the main particles that make up an atom.
Proton = Positive Charge (+)
Neutron = Neutral charge (=)
Electron = Negative Charge (-)
