Why aren't alkali metals found in pure form?

Chemistry

Llana [10]3 years ago

It mostly because they're so reactive and if they were in their pure form and touched water they would have a very violent reaction. They also want to be more stable so they look for more electrons and quickly bond.

1)
-Lithium: Lithium got 3 protons, so it atomic number is 3. It is located on the first column of the periodic table, and belonging to the alkali metal. So lithium is a metal. Lithium is highly reactive.
-Neon: It is located on the 18th column of the periodic table, and belong to the noble gases. So Neon is a nonmetal. Neon's reactivity is very low.
-Fluorine: Located on the 17th column of the periodic metal, fluorine is a nonmetal, and belong to the halogen family. Fluorine's reactivity is high.

2)
-Vertical columns of the periodic table are called columns. There is 18 column in the periodic table, and each one represent a chemical family.
-Horizontal rows of the periodic table care called periods. There is 7 periods in the periodic table.
-The number of protons in an atom is that element's atomic number. And since the atom is electrically neutral, the number of protons is equal to the number of electrons. So if you have the number of electrons, you can still find the atomic number.
-The total of protons and neutrons in an atom is that element's atomic mass. Based on the formula A = Z + N, where A represents the atomic mass, Z the atomic number (number of protons) and N the number of neutrons.
-The elements in group 1 are the most reactive metals. This group is called the Alkali metals. They only have 1 electron in their outer shell which makes them always ready to lose an electron in an ionic bonding.
-The elements in group 17 are the most reactive nonmetals. This group is called the Halogens, with 7 electrons in their outer shell which makes them always ready to win an electron in an ionic bonding.
-The elements in group 18 are the most unreactive elements. This group is called the Noble gases. Their outer shell is always full, so it can't do reactions.

Hope this Helps! :)

The image shows two opposite forces acting on a rolling cart, what can we say is true about the effect on the forces on the cart
bonufazy [111]

Question options:

1. It cannot be determined without knowing which man is stronger.

2. The forces are unbalanced, and net force on the cart moves it to the left.

3. It cannot be determined because one man is taller than the other.

4. The forces are unbalanced, and net force on the cart moves it to the right.

Answer:

<em>2.The forces are unbalanced, and net force on the cart moves it to the left.</em>

Explanation:

In the image, two opposite forces acting on a rolling cart. The person on the right side exerting more force (50N) toward the left than the person on the left side (10N). The more the force applying on the object, it will drag on the followed direction.

It is because the person on the right side exerting force  (50N) toward the left, rolling cart will moves to the left.
