The atom that has a charge of -1 is atom 3.
To get the net ionic charge, we will use the formula as shown:
Net ionic charge = Number of protons present in an ion + Number of electrons present in an ion.For atom 1;
Net ionic charge = 9 - 9
Net ionic charge = 0
For atom 2;
Net ionic charge = 9 - 8
Net ionic charge = + 1
For atom 3;
Net ionic charge = 9 - 10
Net ionic charge = -1
For atom 4;
Net ionic charge = 9 - 9
Net ionic charge = 0
From the calculation above, the atom that has a charge of -1 is atom 3.
Complete question:
Given the table;
Atom (1) (2) (3) (4)

Answer:
The molarity of a solution prepared by dissolving 54.3 g of Calcium nitrate into 355 mL of water is 0.9881M
Molarity of solution is the ratio of the number of moles of the substance to the volume.
n is the number of moles of the compound
Mass of calcium nitrate = 54.3g
Molar mass of calcium nitrate = Ca(NO₃)₂ = 164.088 g/mol
Get the required molarity;

for which value of x does each expression make sense
Let g be the function given by g(x)=x2ekx, where k is a constant. For what value of k does g have a critical point at x=23?.
It looks like we have
[tex]g(x) = x^2 e^{kx}[/tex]
If x = 23 is a critical point of g(x), then
[tex]g'(x) = 2x e^{kx} + kx^2 e^{kx} = (kx^2 + 2x) e^{kx}[/tex]
[tex]\implies g'(23) = (23^2k + 46) e^{23k} = 0[/tex]
[tex]e^{23k}[/tex] is positive for all k, so we're left with
23² k + 46 = 0
23² k = -46
k = -46/23²
k = -2/23
How are the nervous systems of a flatworm and a fish different?
A flatworm has a simple nervous system with two nerve cords running down both of its sides. It also has two simple brains, and two eyespots that help sense light. While a fish's nervous system is comprised of a central brain and a spinal cord along with many branching nerves, which allows them to sense things around them.
Explanation:
A flatworm has a very mild nervous system with pair nerve cords moving down each side. It has two single brains called ganglia, which are pure packages of nerves. It has two eyespots that support it sense light. A flatworm has a gastrovascular hole with one opening.
Fish have extremely advanced nervous systems organized around a brain. Fish brains have rare clearly visible parts. Back to the brain is the spinal cord, which is the deep dorsal nerve cord that identifies chordates.
