Answer:
The C4+ ion has the smallest ionic radius
Explanation:
In the periodic table, the size of an atom increases on going downwards in a group.
On the other hand, in a period, size decreases on going from left to right
The size of cation is smaller than its parent atom.
Lithium-ion (Li+) is the most left so it has the biggest radius.
More to the right ( this means a smaller ionic radius) , we have Berylium-ion (Be2+).
More to the right, so smaller than Be2+, we have B3+
The ion the most to the right, we have C4+
The C4+ ion has the smallest ionic radius
Li+ > Be2+ > Be3+ > C4+
Answer:
Grass, trees, and flowers.
Explanation:
A producer converts the suns energy to make its own food, and a producer uses photosynthesis.
Answer:
Z=26, A = 56, charge +3.
Explanation:
The atomic number is represented by Z. Is equal to the total number of protons that the atom has. Z=26.
The atomic mass is represented by A. The number results from the total sum of protons and neutrons of an atom. Both particles have a weight of 1 uma, are in the nucleus and give the mass to the atom.
Mass number (A) = atomic number (Z) + number of neutrons (N)
A = 26 + 30
A = 56
The net charge of the atom can be calculated by subtracting the negative charges from the positive ones. The positive charges come from the protons and the negative ones from the electrons.
26-23=3
This iron ion has a positive charge +3.
