Why does it make sense that if an atom loses electrons, it is left with a pisitive charage?

Answers

Because atoms are neutral. By neutral, I mean that; there are three main particles that make up an atom. Protons, Electrons and Neutrons. Protons have (electrically) positive charge, electrons have negative and neutrons are electrically neutral. One proton's charge is +1 and one electron's charge is -1. An atom (normally) has the same amount of protons and electrons. Let's say if an atom has two protons and two electrons, the sum of electrical charges of the protons is (two times +1) +2 and sum of electrical charge of electrons is (two times -1) -2 . The total charge of the atom is the sum these. So, (-2)+(2)= 0. That makes the charge of the atom 0, thus makes it neutral. But let's say this atom loses one of its electrons, and now has only one. So one electron (-1) and two protons (+2) in total will be : (-1)+(2) = +1 . +1 is positive, so this makes the charge of the atom positive.

Electrons have a net negative charge, therefore by losing them the atom will become slightly more positive.

How might scientific knowledge about monoculture farming affect societal decisions? Please be sure to answer in complete sentences.Can someone please help me with this?

Answers

in monoculture farming , we produce a single species of a livestock or plant in large quantity.

Eventhough it is very effective, producing a mass number of a single organism in an Area will risk of endangering the existence of a specific nutrient ( because that large number of organism is basically eating the same thing)

which lead to societal decision such as the founding of The Livestock conservancy, or other environmental protection organization

People could choose to practice organic farming, heirloom plants, or use GMOs.Governments could pass laws to limit the use of monoculture farming or require people to use alternate farming methods.

Answer:

The answer to your question is: d

Explanation:

Electron configuration of Carbon.

Atomic number of carbon = 6

a) 1s²2s²2p¹ Number of electrons = 5, This is the electron configuration of Boron.

b) 1s²2s²2p⁴ Number of electrons = 8. This is the electron configuration of oxygen.

c) 1s²2s²p² Number of electrons = 6. This is the electron configuration of carbon. But I think is lacking a number two before p.

d) 1s²2s²2p² Number of electrons 6, This is the correct electron configuration of carbon.
