A material must readily accept electron flow to be a good conductor of electricity. Electrical conductors are electrical charge carriers with electrons that move with ease from atom to atom when charged with voltage. Examples of good conductors are copper, brass, steel, gold, and aluminum.
The answer is C. nebular are star nurseries. When the massive gas being collapsing in its own weight. Local areas of gas begin to coalesce under gravity. Due to enormous pressure, nuclear fusion begins and a protostar is formed. The protostar grows into the sun as more hydrogen fuses at the core. The planetesimal materials at the edges of the protostellar discs coalesce to form planets that orbit the star.
Answer:
The ion has fewer electrons
Explanation:
As Rubidium forms a positive ion Rb⁺ the number of electrons becomes fewer for the atom.
- A positive charge on an ion indicates that the number of protons for the atom is greater than the number of electrons.
- This leaves a net positive charge on the atom.
- For a negatively charged ion, the number of electrons is more than the number of protons because they have gained additional electrons.
- In a neutral atom, the number of protons and electrons are the same.
