Answer:
1. 17 protons / 10 neutrons
2. Scandium
3. Negative
Explanation:
1. The bottom number is the same as the atomic number on top of the abbreviation. To find the # of neutrons, subtract the mass number with the number of protons
2. The bottom number (21) is the number of protons AND the atomic number (the a.n & # of pro. are always going to be the same)
3. Always think about this: if you add electrons, you take away charge - if you take away electrons, you add charge
*Idek if these were the correct correct answers but I tried my best*
The answer is in scientific notation 34^67 42’063 1220.
The correct form for scientific notation is a x 10^b. where a is a number or decimal such that the absolute value of a is greater than or equal to 1 and less than 10, or 1 ≤ |a|. < 10. b is the power of 10 required to make the scientific notation mathematically equivalent to the original number.
To write this number in scientific notation, you must first shift the number of decimal places from the original number by 4 places between 4 and 2. We're subtracting from the exponent because we're shifting the decimal four places to the right.

Hi my dear friend,
The statement that explain how ATP and its phosphate groups are related to energy used in plant process is that ADP gains a phosphate to create ATP, which stores energy for making sugars. These packets of energy in the form of ATP are then broken down to release energy and use that energy in synthesis of glucose.
~Thank you
White light is what the eye sees when wavelengths of all colours reach the eye.
It is a combination of Red, Blue and Green wavelengths of light, that is perceived as white.
