In the polyatomic ion tco4-, tc has a hypothetical charge of 7+. the 99tc isotope is used in medicine for imaging purposes. it has a mass of 98.90625 amu. give the number of protons, neutrons, and electrons for a tc7+ ion.

Answer;

Atomic number Tc = 43 , which is equivalent to the number of protons in nucleus.

Number neutrons = mass number - number of protons = 99 - 43 = 56 neutrons .

Number of electrons = number of protons - charge = 43 - (+7) = 36 electrons

Explanation;

-Atomic number is the number of proton in the nucleus of an atom of a given element. Mass number is the total number of protons and neutrons in the nucleus of an atom. A neutral atom has equal number of protons and neutrons.

-Isotopes are atoms of the same element with the same atomic number but different mass number.

they fuse to form they have half as many chromosomes as a somatic cell of the same individual. b

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)
