What element has 9 protons 10 neutrons? @wbreslyn

Uploaded September 2024 | Updated September 2026, 2 weeks ago

To determine which element has nine protons and ten neutrons, we refer to the Periodic Table. Elements on the table are arranged by increasing Atomic Number, which indicates the number of protons in the nucleus of an atom.

The Atomic Number equals the number of protons for an element: Atomic Number = Number of Protons

By checking the Atomic Number, we see that Fluorine (F) is the element with nine protons. Therefore, Fluorine is the element we're looking for.

Protons are positively charged particles that define the identity of an element, while neutrons add to the atom's mass. With ten neutrons, the total mass number is 19, corresponding to Fluorine-19, the most common isotope of Fluorine.

Rules:

Atomic Number = Number of Protons
Number of Protons = Number of Electrons (for a neutral element)
Mass Number = Number of Protons + Neutrons

$Convert 0.25 L to mL (0.25 Liters to Milliliters) To convert 0.25 liters (L) to milliliters (mL), you can use the following steps. Note that the L will cancel out as you perform the conversion, leaving only mL: Conversion Factor: 1 liter (L) = 1000 milliliters (mL) Start with the quantity you want to convert (0.25 L) and set up a ratio where the original unit (L) is in the denominator and the target unit (mL) is in the numerator, using the conversion factor: Conversion factor: 1000 mL / 1 L Write the quantity you want to convert (0.25 L) as a fraction over 1: 0.25 L / 1 Multiply this fraction by the conversion factor: (0.25 L / 1) * (1000 mL / 1 L) Notice that the units of Liters (L) in the numerator and denominator cancel out, leaving only the units of milliliters (mL): (0.25 * 1000) / (1 * 1) mL = 250 / 1 mL = 250 mL So, 0.25 L is equivalent to 250 milliliters. The units of Liters (L) cancel out during the conversion process, leaving only milliliters (mL) as the final unit.$

$Convert 1.25 L to mL (1.25 Liters to Milliliters) To convert 1.25 liters (L) to milliliters (mL), you can use the following steps. Note that the L will cancel out as you perform the conversion, leaving only mL: Conversion Factor: 1 liter (L) = 1000 milliliters (mL) Start with the quantity you want to convert (1.25 L) and set up a ratio where the original unit (L) is in the denominator and the target unit (mL) is in the numerator, using the conversion factor: Conversion factor: 1000 mL / 1 L Write the quantity you want to convert (1.25 L) as a fraction over 1: 1.25 L / 1 Multiply this fraction by the conversion factor: (1.25 L / 1) * (1000 mL / 1 L) Notice that the units of liters (L) in the numerator and denominator cancel out, leaving only the units of milliliters (mL): (1.25 * 1000) / (1 * 1) mL = 1250 / 1 mL = 1250 mL So, 1.25 L is equivalent to 1250 milliliters. The units of liters cancel out during the conversion process, leaving only milliliters as the final unit.$
