An element with 1 proton is hydrogen (H). However, the given configuration has 1 neutron and 2 electrons.
Typically, hydrogen only has one electron when it is in its neutral state. The presence of 2 electrons indicates that this atom has gained an extra electron, which makes it a negative ion (specifically, a hydride ion, H⁻) since it has more electrons than protons.
So, to summarize:
- The element is hydrogen (with 1 proton and 1 neutron, making it deuterium).
- It has 2 electrons, which makes it a negatively charged ion (ionized state).
