The answer for Plato will be letter A
A sample of material is found to have a mass if 33.03 grams (g), and a volume of 2.624 ml, hence the metal is Silver.
∴ Silver = 12.59 g/mL
The elements of group 11 (Cu, Ag, and Au) are called coinage metals because they are used in minting coins. These metals are malleable. They have the ability to get converted into sheets.
The coinage metal comprise, at a minimum, those metallic chemical elements which have historically been used as components in alloys used to mint coins.
The coinage metals have the highest electrical and thermal conductivities of all the metals, and they are also the most ductile and malleable.

Answer:
when rutherford performed his experiment, only 1 in 20,000 alpha particles bounced straight back or were deflected greatly. the rest went straight through the gold foil. e) based on this evidence, what is in atom's center? positively charged particles.
Explanation:
Ionization is a process in which an electron present in the outermost orbital of an atom gets knocked out by absorbing an appropriate amount of energy. Release of electron from a neutral atom results in the formation of a cation- a positively charged ion.
Rubidium (Rb) is an alkali metal with a valence electron configuration of 5s¹. Ionization results in the loss of this '5s' electron forming a Rb+ ion. The reaction can be expressed as:
Rb (5s¹) → Rb⁺ (5s⁰) + e⁻
The flame test is used to visually determine the identity of an unknown metal or metalloid ion based on the characteristic color the salt turns the flame of the bunsen burner
