LITHIUM-ION.
Explanation:
ATOMIC STRUCTURE -
The smallest unit has the characteristics property of an element.
An atom consists of electron revolving around the nucleus in fixed orbits.
The Nucleus is a centrally located mass formed by the protons and the neutrons.
The atomic mass of an element is given as the sum of the protons and neutrons.
The Atomic number is equal to the number of protons or electrons.
In the given element element,
Atomic mass = 3 + 4 = 7
Atomic number = 3
As the number of protons in the atom is greater than the number of electrons by 1. Therefore, the element is a cation.
The element with atomic number 3 and atomic mas 7 is LITHIUM-ION.

In this case, 58.703 has five significant figures because the 3 at the end is significant and therefore makes the 0 significant as well. Since there are 5 significant figures, we need to round off the 7 to get 58.7, which has three significant figures.
Hope this helps.
