A positively charged atom has? 1. gained protons. 2. gained electrons. 3. lost electrons. 4. lost protons.
1 answer:
Answer:
3. lost electrons.
Explanation:
An atom that has lost an electron is positively charged because the number of protons is now greater than the number of electrons in the atom.
Protons are positively charged particles in an atom. Electrons are negatively charged particles. Neutrons do not carry any charges.
If the number of protons and electrons are the same, the atom has no charge
If the protons > electrons, the atom becomes positively charged
If electrons > protons, the atom becomes negatively charged.
Atoms becomes charged by losing or gaining electrons.

epicycles were orbits within orbits used to explain discrepancies between expected and observed planetary movement, including the appearance of planets slowing down, speeding up, and moving backward.
micrometer is used to measure the diameter of a thin wire
Answer:
464.69 m
Explanation:
First car
Second car
Distance = Speed × Time
Here, the time taken and the distance traveled will be the same
Equating the two equations
So, the first would have to move in order to overtake the second car.
