An atom with 3 protons, 4 neutrons, and 3 electrons can be identified as lithium (Li). In order to find an atom with similar chemical properties, we need to look for an atom in the periodic table that has the same number of valence electrons.
Valence electrons are the electrons in the outermost energy level of an atom and are responsible for determining the chemical properties. Lithium (Li) has 1 valence electron.
The atom that has the closest number of valence electrons is an atom with 4 protons, 4 neutrons, and 3 electrons. The atomic number 4 corresponds to beryllium (Be). Beryllium also has 2 valence electrons, making it similar in chemical properties to lithium.
So, the correct response is:
4 protons, 4 neutrons, and 3 electrons.
To determine which atom would have similar chemical properties to the given atom, we need to consider the number of protons and electrons.
The given atom has 3 protons and 3 electrons. So, we need to find an atom with the same number of protons and similar number of electrons.
Among the options provided, the atom with 4 protons and 3 electrons (4 protons, 4 neutrons, and 3 electrons) will have similar chemical properties to the given atom.
Therefore, the correct answer is: 4 protons, 4 neutrons, and 3 electrons.
To determine which atom would have similar chemical properties to the given atom (3 protons, 4 neutrons, and 3 electrons), we need to consider the atomic number, which is determined by the number of protons in an atom.
Given that the given atom has 3 protons, we need to find an atom with the same number of protons. Looking at the options provided, we can eliminate the atoms with 4 protons and 10 protons.
Now let's compare the remaining options:
- 12 protons, 12 neutrons, and 12 electrons: This atom has 12 protons, which is not the same as the given atom with 3 protons. Eliminate this option.
- 4 protons, 4 neutrons, and 3 electrons: This atom has the same number of protons as the given atom. However, it has a different number of neutrons. Therefore, it is not likely to have similar chemical properties.
- 11 protons, 11 neutrons, and 11 electrons: This atom has 11 protons, which is not the same as the given atom with 3 protons. Eliminate this option.
- 10 protons, 12 neutrons, and 10 electrons: This atom has a different number of protons from the given atom, so it is not likely to have similar chemical properties.
Based on the above analysis, we determine that the atom with 4 protons, 4 neutrons, and 3 electrons would have similar chemical properties to the given atom.
