Answer:
the sum of the numbers of protons and neutrons present in the nucleus of an atom.
Answer:
- atomic #= 1
- protons equals one
- Number of neutrons equals to 0
- number of electrons equal to 1
- mass number equals to 1
2.
- atomic number equals to 1
- Protons equals to 1
- number of neutrons equals to 0
- number of electrons equals to 0 because the plus sign means that it loses an electron
- mass number equals to 1
3.
- atomic number 17
- number of protons 17
- number of neutrons 18
- number for electrons 18 Because negative sign means It's an anion which means it gains an electron
- mass number 35
4.
- 12
- 12
- 12
- 10 loses 2 its a cation
- 24
5.
- 47
- 47
- 108-47 = 61
- 46 loses 1
- 108
6.
- 16
- 16
- 32-16 =16
- 18 it gains 2 electrons
- 32
there u go
Answer:
I think its might be 1 because the ionic numbers for CA is +2 and for P its +3
I believe pH = -log[H+]
Also, 14 = pH + pOH
Therefore pH = 14 - pOH
pH = 14 - 4.01
pH = 9.99
9.99 = -log[H+]
Solve for H+
