"If an electrically neutral atom has 4 protons and 4 neutrons and it gains 2 electrons, what is its electrical charge?"

Chemistry

mariarad [96]3 years ago
4 0

Explanation:

When an atom is neutral then number of protons equal number of electrons. Therefore, a neutral atom with 4 protons and 4 neutrons will also have 4 electrons.

It is known that when an atom gain electrons then it acquires a negative charge and when an atom loses electrons then it acquires a positive charge.

Therefore, when the given neutral atom gains 2 electrons then it will acquire a negative charge.

Calculate the density from the following information: A red block had a mass of 15.7 g. It was placed into a graduated cylinder
matrenka [14]

Answer:

Density should be 8.5

Explanation:

When you subtract 17.2-10.0 for water displacement you get 7.2 which is the volume and you divide it by 15.7 so your equation will be 15.7/7.2 = 8.5

Goshia [24]

Answer: it started too rot over time mold over time and decay and if you cooked a apple it would melt like ice cream cause of the heat waves and if the apple is surrounded by air i think what would happen it would still rot I guess but i wouldnt know for sure cause things with air take time too rot and things with air rot faster and slicing the apple into more pieces would make it decay or rot or mold faster cause its open and accepting everything it sees like bacteria bugs all that

Explanation: like the longer a apple is left half open it starts too rot then mold over time getting all bad and not good too eat or decay

read it all the stuff is in there i think

How does the electron arrangement change moving vertically down a group?​
vampirchik [111]

Answer:

Electrons arrangement change is almost constant down the group, hence nuclear charge is almost constant.

But the energy levels on which electrons are arranged increase down the group, hence shielding or screening effect increases.
