what is the total charge? plz help!
Answer:
0
Explanation:
Protons have a positive + charge.
Neutrons have a neutral (0) charge.
Electrons have a negative - charge.
In order to determine the charge of an atom, we only look for the protons and neutrons.
We are given 2 protons and 2 electrons
+2 charge + -2 charge = 0 charge.
This atom is a neutral atom.

Which family does this element belong to? It sa reddish brown liquid with
an amber vapor, It is very reactive and it has a pungent odor that is
irritating to the skin, eyes, and respiratory
Alkali Metals
Alkaline Earth Metals
Halogens
Noble gases
Answer:
The correct answer is - halogen.
Explanation:
The physical properties of the given elements are identical to the physical properties of the free bromine which is a reddish-brown liquid that has a pungent odor and highly reactive. It has an appreciable amber vapor at 25 degrees (room temperature).
Bromine is a halogen and like other halogens, it is also present in the diatomic molecule and located in the 17th group or VII A group of periodic tables. Exposure of the bromine causes irritation to the eyes, skin and respiratory system.
Is the electron arrangement in a sodium ion
similar to neon or to argon?
Answer:
Just as some elements attain a noble gas configuration by gaining some extra electrons, other elements can more easily gain that configuration by losing some electrons. For a sodium atom, it is simply closer to get to the same configuration as neon than it is to get to the same configuration as argon.

(50 POINTS) Why does the radius of an atom increase as you go down a group on the periodic table?
A) because you are increasing the size of the electrons, which takes up more space
B) because you are adding another outer level of electrons, further from the nucleus
C) because you are adding more neutrons, which reduces the attraction between proton and electron
D) because you are decreasing the pull by the nucleus, allowing the electrons to travel further away
Answer:
B
Explanation:
The atomic radius increases as you go down a group in the periodic table. Atoms get larger because more electrons are being added in higher energy levels, and each energy level is further from the nucleus than the last. Therefore, the atomic radius increases as you go down a group.
The science of life or living matter in all it’s forms and phenomena? What’s it’s vocab answer?
Answer:
Biology
Explanation:
8. Converting Units The volumes in your data are in millimeters, which are equivalent to cubic centimeters, cm3. But your areas are in units of square meters (m2). To combine these, you will have to convert to similar units. Convert one of your volume measurements from units of cm3 to units of m2, showing your work. (Remember that 1 ×106 cm3 = 1 m2.)
Answer:
This question is a practical question and hence incomplete
Explanation:
However, there are some steps that can be followed to achieve the aim of this question.
To convert millimeters (mm) to cubic centimeters (cm³), the value in millimeter will have to be divided by 1000. This is because 1 mm equals 0.001 cm³. Hence, if the volume in the data is 30 mm, the equivalent in cm³ will be
30/1000 = 0.03 cm³
OR
1 mm ⇒ 0.001 cm³
30 mm ⇒ ?
Let's assume the unknown (?) is X
1 × X = 30 × 0.001
X = 0.03 cm³
Hence, 30 mm equals 0.03 cm³
Also, to convert any volume from cubic centimeter (cm³) to square meter (m²), you will divide the unit in cm³ by 1 × 10⁶ (1,000,000). To convert the value obtained earlier (0.03 cm³ or 3 × 10⁻² cm³) to m², you will
1,000,000 cm³ ⇒ 1 m²
0.03 cm³ ⇒ ?
Let's assume the unknown (?) is Y
1000000 × Y = 0.03 × 1
Y = 0.03/1000000 OR you can write it as 3 × 10⁻² × 10⁻⁶
Y = 3 × 10⁻⁸m²
Hence, 0.03 mm equals 3 × 10⁻⁸ m²

Which word describes an artificial pond with raised edges used for agriculture?
shaduf
paddy
aqueduct
chinampa
Answer:
Paddy
Explanation:
he word paddy is used to describe an artificial pond with raised edges which are used for agriculture.
The word describes an artificial pond with raised edges used for agriculture is paddy. Therefore, option B is correct.
What do you mean by an artificial pond ?Seldom do artificial ponds have a natural outflow and entrance. This indicates that they only get fresh water from rain and direct activity, such a partial water change.
Ponds have a variety of functions, including providing water for farming and livestock, assisting in habitat restoration, acting as fish hatcheries, being parts of landscape architecture.
The paddy ponds are man-made ponds with elevated sides that are utilised for agriculture. These ponds are primarily used to easily supply crops with a suitable amount of water. These ponds are kept full of water, and rainwater is also collected and stored there.
Thus, option B is correct.

In your own words, describe how the energy of a pendulum is changed as it moves through one cycle of its motion. Pls help online school sucks
In a perfect world without air resistance, the top of the swing would have the most potential energy, but the least amount of kinetic energy. As the pendulum falls down, it gains more kinetic energy as it travels faster due to gravitational acceleration but loses more potential energy as it loses height. The total amount of energy in the system (the sum of kinetic and potential energy) stays the same.
The energy of a pendulum is changed from Kinetic to Potential Energy (and vice-versa) when it moves through one cycle of its motion.
What is Kinetic Energy ?The kinetic energy of an object is the energy that it possesses due to its motion and is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.
When we move the bob of the pendulum to start the movement you "charge" it with Potential Energy (Gravitational) by varying its position (height) in relation to the ground.
When we release the bob it moves towards the equilibrium position changing Potential into Kinetic Energy (through the movement with Velocity).
At the equilibrium point the bob doesn't stop but goes on up to the same height "re-charging" it with Potential Energy.
The sum of Kinetic (K) and Potential (U) Energy (called Mechanical Energy is always the same:
E = K + U = constant
Therefore, The energy of a pendulum is changed from Kinetic to Potential Energy (and vice-versa) when it moves through one cycle of its motion.
