Answer:
ionic charge
Step-by-step explanation:
So, an atom with an ionic charge of +2 has two more protons than electrons. The element calcium, for example, has atomic number 20 so the atom has 20 protons. The calcium ion with a positive +2 charge has two more protons than electrons.

360+45=405 hope this helps
Part I)
The module of vector AB is given by:
lABl = root ((- 3) ^ 2 + (4) ^ 2)
lABl = root (9 + 16)
lABl = root (25)
lABl = 5
Part (ii)
The module of the EF vector is given by:
lEFl = root ((5) ^ 2 + (e) ^ 2)
We have to:
lEFl = 3lABl
Thus:
root ((5) ^ 2 + (e) ^ 2) = 3 * (5)
root ((5) ^ 2 + (e) ^ 2) = 15
Clearing e have:
(5) ^ 2 + (e) ^ 2 = 15 ^ 2
(e) ^ 2 = 15 ^ 2 - 5 ^ 2
e = root (200)
e = root (2 * 100)
e = 10 * root (2)
2(5x+8)=6x+20
10x+16=6x+20
4x+16=20
4x=4
x=1
The total surface area of this triangular prism is 928cm
