Which scientist's atomic model is most recent?
A. Dalton's
B. Rutherford's
O c. Thomson's
D. Bohr's
Answers
Answer:
D. Bohr's
Explanation:
I just did the test, and got it right! Hope this helps.
It was Niels Bohr who discovered the modern atomic model. This model revealed the revolution of electrons and determination of energy levels and momentum of electrons. Hence, option D is correct.
What was atomic model?Various atomic models discussed about the structure and electronic properties of atom. It was Dalton who found that atom is indivisible and combination of atoms make a compound.
Later J.J . Thomson discovered electrons the subatomic particles. But this model does not found the orbitals for electrons and energy levels. Rutherford proposed then the nuclear model of atom.
Nuclear model of atom described that the nucleus contains the positively charged particles protons and the negatively charged particles electrons are revolving around the nucleus.
Later Bohr explained the revolution of electrons around the nucleus with the aid of quantum mechanics and he found that the electrons revolves through a circular paths of fixed energy. By this model momentum and energy of electrons can be calculated.
Hence, Bohr's model is most recent.

Having freckles (F) is dominant over not having freckles (f). A parent with freckles is crossed with a parent without freckles. The Punnett square shows the possible genotypes of the offspring.
What is the genotype of each square?
A: FF Ff ff
B: FF Ff ff
C: FF Ff ff
D: FF Ff ff
Answers
Answer:
A: Ff
B: ff
C: Ff
D: ff
Explanation:
You basically look at the box it's asking for, let's use A as an example. On the top where the A column is there's F, so that's one of the thingys I forgot what they're called. Next look at the row of A, and there's f. Put the 2 together and you get Ff. Reminder that any uppercase ones come first.
A=Ff
B=ff
C=Ff
D=ff
How do you determine if an element is metal or non-metal?
Answers
Answer: If the outermost shell has 1–4 electrons, it is a metal.
If the outermost shell has 5–7 electrons, it is a non-metal.
Example - Carbon
atomic number - 6
electron configuration - 2,4
Meaning it has 4 electrons in its outer most shell which makes it a METAL.

An element has a mass of 39.2 and an atomic number of 19. How many protons does this element have? How many neutrons? How many electrons?
Answers
Answer:
19 protons, 19 electrons, and 3 neutrons
Explanation:
the atomic number is 19 so the protons are the same, 19, and the electrons are the same as the proton, because protons are positive and electrons are negative so they have to balance out and the neutrons ➗ mass number by the atomic number.

Answers
Answer:
1) 157 Neutrons, 2) the decimal is simply is due to isotopes, because the elements atomic mass is an average of these isotopes multiplied by its abundance(or percentage on earth.) For Mercury, it has many isotopes(an element with a different mass number, logically the atomic mass listed on the periodic table as a mass has 100% abundance, therefore this is used to find the most abundant mass for that particular element/molar mass) likewise, Mercury has an atomic mass of 200.59 u, as one mol of Hg(mercury) is 200.59 grams.

The formula for Neutrons in an atom of an element is calculated by finding the

Carbon dioxide is added to the atmosphere by burning fossil fuels.
Carbon dioxide is a waste produce of respiration.
Answers
Answer:
B. is the answer. :)
Explanation:
have a good day <3
The carbon cycle is the rotation of the carbon and its compound in the atmosphere. carbon is added to the atmosphere by burning fossils and is a waste product of respiration. Thus, options C and D are correct.
What is a carbon cycle?A carbon cycle is a biogeochemical cycle that involves the reuse of the carbon from various sources that involve the atmosphere and organisms. The cycle repeats itself again and again.
When fossil fuel is burnt carbon dioxide along with some gases are released into the atmosphere. Also, carbon dioxide is a waste product of cellular respiration. Most of the carbon is present in rocks, oceans, and the atmosphere.
Therefore, the burning of fossils releases carbon.
