a.
To determine:
The element which is more likely to be a metal out of the given elements E and X.
Introduction:
Atoms consist of three subatomic particles namely proton, electron, and neutron. Out of these subatomic particles only electrons are involved in bonding. The formation of a bond between two species is always due to the involvement of electrons. It either undergoes loss of electrons or gains electrons in order to complete the outermost shell of electrons.
b.
To determine:
The element which is more likely to be a nonmetal out of the given element E and X.
Introduction:
Atoms consist of three subatomic particles namely proton, electron, and neutron. Out of these subatomic particles only electrons are involved in bonding. The formation of a bond between two species is always due to the involvement of electrons. It either undergoes loss of electrons or gains electrons in order to complete the outermost shell of electrons.
c.
To determine:
The formula of the compound formed from elements E and X.

Using only the periodic table, place the following atoms in order of increasing atomic radius: C, Ba, 0, Ca, and Ge. 21. What types of elements are bonded together to make an ionic compound? Give three examples of ionic compounds. Identify the types of elements that make up the compound in each example. 27. Describe how the physical state of a substance at room temperature depends on the strength of the intermolecular forces between the particles of the substance.arrow_forward1. Whenever chemists observed atoms reacting with each other, they noticed that the sum of their group numbers usually equaled eight, or multiples of 8 (16, 24, 32, 40, etc.). This is called The Rule of Eight. How does this Rule of Eight work in understanding chemical formulas?2. Chemical formulas are written to show how many atoms of each element are bonded together to make a molecule of a substance. For example, C6H12O6 is the chemical formula for one molecule of sugar.3. Look at water: H20. By looking at this formula, you know that it takes _____ hydrogen atom(s) to bond with _______ oxygen atom(s).4. Now, add the group numbers. Hydrogen has a group # of 1A. Oxygen has a group number of 6A. Two hydrogens (1 + 1) and one oxygen (6) equals a total of 8. The Rule of Eight!5. Try another simple one, table salt (sodium chloride, NaCl). The formula tells you that it takes ______ sodium atom(s) to bond to ______ chlorine atom(s). Add the group numbers: The group # for…arrow_forward1.
