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.
An atom has 3 protons, 4 neutrons, and 3 electrons. Use the periodic table to determine which atom would have similar chemical properties to this atom.(1 point)Responses12 protons, 12 neutrons, and 12 electrons12 protons, 12 neutrons, and 12 electrons4 protons, 4 neutrons, and 3 electrons4 protons, 4 neutrons, and 3 electrons11 protons, 11 neutrons, and 11 electrons11 protons, 11 neutrons, and 11 electrons10 protons, 12 neutrons, and 10 electrons
