The atomic and mass numbers of the daughter isotope, which emits a beta particle 91, 232
Isotopes belong to the same elemental family but have different ratios of neutrons to protons, making them different substances. On the Periodic Table, each element's atomic number is based on how many protons are in its nucleus.
Isotopes are two or more different atom types that share the same atomic number and place in the periodic table but have different quantities of neutrons in their nuclei, resulting in various nucleon numbers. Despite having various atomic weights and physical characteristics, they exhibit roughly the same chemical activity. Isotopes are variations in the mass number, "A," of an element's atoms that share the same number of protons (atomic number, "Z") but a different number of neutrons.

Answer:
This work was done in the European plum (Prunus domestica). The gene for PPV coat protein was separated from the PPV virus and inserted into the plum DNA, which was then regenerated and grown into complete plum trees. These trees now had the additional gene in their DNA and became resistant to PPV.
Answer:
6.941 grams
Explanation:
The molecular formula for Lithium is Li. The Si base unit for amount of substance is mole. 1 mole is equal to 1 moles Lithium, or 6.941 grams
Mg + Cl₂ -----> MgCl₂
24g 1 mol
24g Mg ---- 1 mol Cl₂
Xg Mg ------ 2 mol Cl₂
X = 2×24
<u>X = 48g Mg</u>
