D)Cation is the answer. A cation is a positive ion fromed by the removal of electrons from the outermost shell of an atom.

Let's take Na ( Sodium ) whose At. No is 11 as an example.
When we arrange them in electronic configuration Sodium has 3 shells. 2 in its innermost shell (K), 8 electrons in its 2nd shell which is named as 'L' & lastly 1 electron in its outermost shell (M).

We know that in an atom the no. of protons, neutrons and electrons are equal.

In case of sodium, when only electrons are reduced while protons remained same. Previously, the No. of protons and electrons were equal. But this time, There is an extra proton(+). This is the reason when an electron is removed we get a cation.

There are two factors that causes atoms to loose electrons -

1) Atomic Size

2) Nuclear Charge

Snowcat [4.5K]

Answer:

1000mg= 1g

1L= 1000 mL

160cm = 1600mm

1.4km= 1400m

109 g = 0.109kg

250m= 0.250 km

80cm= 0.8 m

75mL= 0.075L

5.6m= 560 cm

6.5g= 6500mg

170.4m= 17040 cm

564 Dg = 5640 g

58 dg = 5800 mg

600 L=  0.6 KL

0.0923Km= 92300 mm

Explanation:

1 mg = 1x10⁻³ g

1 g = 1000 mg

1 g = 10 dg

1 g = 1x10⁻³ kg

1 Dg = 10 g

1 dg = 100 mg

1 L = 1000 mL

1 L = 1x10⁻³ KL

1 mL = 1x10⁻³ L

1 km = 1000 m

1 km = 1x10⁶ mm

1 m = 1x10⁻³ km

1 cm = 1x10⁻² m

1 cm = 10 mm
