Mass number= atomic number + number of neutrons.
A=Z+N
Z=number of protons=12
N=12
A=12+12=24
If, we have 12 protons and 10 electrons, the charge of this ion is +2
Therefore: mass number:24; charge: +2
Answer: a. mass number: 24; charge: +2
Hello there! It sounds like she intends to pursue a career in Genetic engineering
Genetic engineering is "the deliberate modification of the characteristics of an organism by manipulating its genetic material". Since Yvonne is interested in the possibility of modifying human DNA, this seems to be the perfect fit since it involves modifying DNA.
Hope this helps, have a great day!
Answer: This is a very unstable atom. It is a cation, meaning it is positively charged. This atom doesn't have an equal amount of neutrons to protons, so it is extremely unstable. It has a charge of +1 because it is missing a negatively charged particle, making a positive charge.
Explanation:
Answer:
This is because the carbon dioxide gas that dissolved in the water is not very soluble. ... After the citric acid solution and baking soda react, carbon dioxide gas is formed, along with other products.
