what that guy said
Explanation:
because he provides evidence
Carbon is an important compound on the earth. This is really visible in Carbon Dioxide. The valence electrons are important because they allow many different types of bonds to occur.
Answer: when heated and for answer dont forget to hit the brainliest
Explanation:
Answer:
2.88 × 10⁻¹⁸ C
Explanation:
The charge on a proton and electron are the same and it is = 1.6 × 10⁻¹⁹ C
The net charge electric charge of an iron atom = (number of proton × charge on a proton) + ( number of electron × charge on an electron ) = 26 (e) + 8 (-e) = 26 e - 8 e = 18 e = 18 × 1.6 × 10⁻¹⁹ C = 2.88 × 10⁻¹⁸ C
Earth pulls downward due to gravitational force. Electric current in coils produce electromagnets which repel the superconducting dimagnetic material with equal force upwards.
